Orange coat color in cats is due to an X-linked allele (Xo) that is codominant to the allele for black (X+). Genotypes of the orange locus of cats in College Park were determined and the following data were obtained: XoXo 16 XoX+ 78 X+ X+ 105 X+Y 112 XoY 39 Calculate the frequencies of the Xo and the X+ alleles for this population.
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.
