The relative fitness values of three genotypes are wA/A =1.0, wA/a = 1.0, and wa/a = 0.7.a. If the population starts at the allele frequency p =0.5, what is the value of p in the next generation?b. What is the predicted equilibrium allele frequency ifthe rate of mutation of A to a is 2 × 10−5?
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.
The relative fitness values of three genotypes are wA/A =
1.0, wA/a = 1.0, and wa/a = 0.7.
a. If the population starts at the allele frequency p =
0.5, what is the value of p in the next generation?
b. What is the predicted equilibrium allele frequency if
the rate of mutation of A to a is 2 × 10−5?
