Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

Apparently the dominant forms are often less severe. Eric's form of RP is Usher's Syndrome, which is an autosomal recessive inheritance (i.e., you must get a copy of the defective carried on one of the chromosomes that determines sex. Usher's Type II is recessive, so for Eric this means that both his Mom and Dad are carriers of this condition. His brother, Dirk, does not have any symptoms of RP. gene from your Mom and one from your Dad).

- The ability to roll the tongue into a tube is a single-gene dominant trait governed by the R The recessive allele for lacking the ability is r. A woman who can roll her tongue has a father who cannot. What is her tongue-rolling genotype? RR Rr rr either A or B cannot tell from the information providedPart B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…For each phenotype below, list the genotypes (remember to use the letter of the dominant trait) Curly hair is dominant to straight hair. . ____ straight ____ curly ____ curly
