42. Albino In conclusion, albinism is not a very well studied mutation in genetics so thereisn't very much information out there and the definition of an albino is http://www.compusmart.ab.ca/kbush/albino.htm

What is an Albino? The following information comes from Gilbert, S. F. 2000. Developmental Biology Sixth Edition. Swarthmore College. Sinauer Associates, Inc. Publishers, Sunderland, Massachusetts U.S.A. The albino gene in rabbits (From Griffiths, A.J., Miller, J.H., Suzuki, D.T., Lewontin, R.C., and Gelbart, W.M. 1996. An introduction to Genetic Analysis Sixth Edition. W.H. Freeman and Company, New York U.S.A) . Variants of the "C" gene in rabbits can lead to 4 genotypes: full colour (CC, Cc ch , Cc h ,or Cc), chinchilla (c ch c ch , c ch c h ,or c ch c), Himalayan (c h c h or c h c), and albino (cc). As you can see, the "C" gene is involved in a dominance hierarchy. The Full Colour gene "C" is dominant to the Chinchilla gene "c ch " which is dominant to the Himalayan (albino with black extremities) gene "c h " which is in turn dominant to the Albino gene "c". Q: What can cause the albino phenotype? A: Mutations - mutations in an individual occur in either the somatic tissue (tissue not associated with the gonads and germ cell production) or the germinal tissue (tissue associated with the gonads and germ cell production) (From Griffiths, A.J., Miller, J.H., Suzuki, D.T., Lewontin, R.C., and Gelbart, W.M. 1996. An introduction to Genetic Analysis Sixth Edition. W.H. Freeman and Company, New York U.S.A)

Click on topic of interest: Basic Genetics Genetic Example (White Cat) Mutations Body Conformation Genes ... The Bengal Cat BASIC GENETICS Each feline is incredibly unique, as we all know. Basically, the study of genetics is the fascinating study of the evolution of life itself , on a much smaller scale. The method of passing the genetic code of the parents to the next generation through the "germ" cells (ova in females and sperm in males), is one of the most awesome and incredibly beautiful processes in nature. Long, irregular threads of genetic material called chromosomes are found within the nucleus of a cell, and they are arranged in pairs. Cats have 19 pairs of chromosomes; people have 23 pairs of chromosomes. For cats, it is these 38 chromosomes which make up the unique, individual "blueprint" for that animal. The chromosomes are covered with hundreds of thousands to millions of light and dark colored bands which are the actual genetic codes, called genes. Each gene controls a single feature or a group of features in the makeup of an individual. Even this concept becomes more complicated as many of the genes interact with other genes! A single feature of an individual may be controlled by many different genes, which makes "mapping" of the genes very difficult, and for cats, only a few major genes have been mapped out to date.

Feline Genetics R. Roger Breton Nancy J Creek Continued from page 3 The Color-Density Gene The third and last of the genes controlling the coat color is the color-density gene. This gene controls the uniformity of distribution of pigment throughout the hair and comes in two alleles: dense, "D", and dilute, "d". The dense allele, "D", is wild, is dominant, and causes pigment to be distributed evenly throughout each hair, making the color deep and pure. A dense coat will be black, dark brown, medium brown, or orange. The dilute allele, "d", is mutant, is recessive, and causes pigment to be agglutinated into microscopic clumps surrounded by translucent unpigmented areas, allowing white light to shine through and diluting the color. A dilute coat will be blue (gray), tan, beige, or cream. The Eight Cat Colors All possible expressions of the color, orange-making, and color- density genes produce the eight basic coat colors: black, blue (gray), chestnut or chocolate (dark-brown), lavender or lilac (tan), cinnamon (medium brown), fawn (beige), red (orange), and cream.

Genetics Gondar Design Biology Genetics is the study of heredity. If you understand genetics you will be able to work out why you look like each of your parents and your siblings (brothers and sisters) but are not exactly like any one of them: unless you have an identical twin. Don't be worried in the exam if you are given an example which you have not studied: if you understand the principles you will probably find GCSE question on genetics quite easy. Don't you just hate it when you are lying in your pram gurgling away and all your dad's family come up and say "Ooooh doesn't he look just like his dad?" and then all your mum's family come and say "Oooh doesn't she look just like her mum?".

PRINT PAGE An example of recessive inheritance: albinism Our facial features, just like the rest of our body, are 'designed' by our genes. Albinism is a group of conditions where people are born with little or no pigmentation in their eyes, skin and hair (or sometimes just in the eyes alone). It occurs because they have inherited one or more faulty genes that do not produce the usual amounts of a pigment called Melanin. Apart from their physical appearance, those with the condition can experience a number of associated problems, depending on which genetic type they have. Particularly common are problems with vision and from skin burning in sunlight. About 1 in 17,000 children born in the UK have some type of Albinism. It affects all races, but may be slightly more common in some, such as those of black African origin. The genetics of albinism Several different genes are involved with pigment production, including genes on chromosomes 9,10, 11,13,15 and X, but it's not clear exactly what role each of these plays in the condition. In most cases there is no family history and the children are born to parents with normal pigmentation for their race.

Medline Citation ABSTRACT Background Type II (tyrosinase-positive) oculocutaneous albinism is an autosomal recessive disorder that has recently been mapped to chromosome segment 15q11-q13. The frequency of this disorder is greatly increased in patients with Prader-Willi or Angelman syndrome, both of which involve deletions of chromosome 15q. The P protein is a transmembrane polypeptide that may transport small molecules such as tyrosine, the precursor of melanin. The P gene is located in chromosome segment 15q11-q13. Methods We studied the tyrosinase and P genes in three patients with type II oculocutaneous albinism, one of whom also had Prader-Willi

YORK CHOCOLATE GENETICS Author: Dr. Fulvio Bresciani The York Chocolate could be considered genetically a very particular cat breed. Few phenotypic peculiarities of the York are object of scientific studies and very interesting researches in genetic applications and not only. Preservation, diffusion and universal recognition of the York Chocolate in the world must be considered a mission not only because of the intrinsic beauty but especially because its genetic particularities allows to many experts to develop new discoveries and genetic theories. The phenotypic peculiarities characterizing the breed may be considered perfectly fixed and transferable constantly on all descendants. These peculiarities may be listed as follows: color hair, white displacement on the coat and under-coat’s lack. Today, every world feline lovers and genetic experts are very interesting on the last two features of the York. The lacking under-coat Lacking under-coat surely is the most important phenotype characterizing the breed. Many researches and crossing experiments would confirm the existence of a gene controlling the under coat expression. In particular, collecting many informations from York Chocolate pedigree and applying statistical formulations on a lot of observations the Mendel lows would result perfectly verified.

Key terms and goals of population genetics In the early days of genetics it was assumed simplistically that allelic diversity in a population (a group of interbreeding individuals) is rather small, i.e. there exists one common wild-type allele and at most one or a few mutant alleles. However, with the advent of more sophisticated analytical techniques, it became apparent that natural populations harbor significant allelic diversity. a) Isozyme analysis : A specific enzyme (e.g. alcohol dehydrogenase) can exist in different allelic versions that can be distinguished by their

58. Albinism genetics of albinism For nearly all types of albinism both parents mustcarry an albinism gene to have a child with albinism. Because http://eyeconditions.homestead.com/Albinism.html

Albinism One person in 17,000 in the U.S.A. has some type of albinism. Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backgrounds. Often people do not recognize that they have albinism. A common myth is that by definition people with albinism have red eyes. In fact there are different types of albinism, and the amount of pigment in the eyes varies. Although some individuals with albinism have reddish or violet eyes, most have blue eyes. Some have hazel or brown eyes. Vision Problems: Vision problems in albinism result from abnormal development of the retina and abnormal patterns of nerve connections between the eye and the brain. It is the presence of these eye problems that defines the diagnosis of albinism. Therefore the main test for albinism is simply an eye exam. Types of Albinism: While most people with albinism have very light skin and hair, not all do. Oculocutaneous (pronounced Ock-you-low-kew-Tain-ee-us) albinism involves the eyes, hair, and skin. Ocular albinism involves primarily the eyes, while skin and hair may appear similar or slightly lighter than that of other family members. Researchers have identified several other genes that cause forms of albinism. In one form of albinism, the Hermansky-Pudlak syndrome, there can be problems with bleeding, and with lung and bowel disease as well. Hermansky-Pudlak syndrome is a less common form of albinism, but should be suspected if a child with albinism shows unusual bruising or bleeding.

Genetics Research A major emphasis of research in the Genetics Division has been the genetic regulation of melanin biosynthesis in the model system of human oculocutaneous albinism. Clinical, biochemical and molecular studies have provided information for accurate definition and classification of oculocutaneous albinism. Important genes involved in the synthesis and regulation of melanin synthesis have been identified, cloned, and analyzed for mutations responsible for loss of function. The molecular analyses have led to the current classification of oculocutaneous albinism based on the involved genes rather than the pigment phenotype, and this has aided in family counseling and planning. Current work includes the expression of normal and mutant tyrosinase for biochemical characterization, and for crystallization and three-dimensional structural analysis, to gain insight into basic enzyme biology and mechanisms of dysfunction. A second area of emphasis for the division involves gene mapping and localization for complex diseases. To accomplish this, a high-throughput automated DNA sequencing laboratory has been established, under the direction of Dr. Oetting. Mapping projects have involved breast cancer and myopia is the past and currently involved asthma, as part of a four-center NIH-funded collaborative study (CSGA). Dr. Malcolm Blumenthal, Allergy, is the PI and Drs. King and Oetting are co-investigators on the study, and the gene mapping is performed in the division laboratory.
