The fraggles are a population of mythical, mouselike creatures that live in underground tunnels and chambers beneath a large vegetable garden that supplies their food. They can reproduce VERY quickly! Of the fraggles currently in this population, 372 have green fur and 182 have gray fur. Green fur is controlled by a dominant allele F and gray fur by a recessive allele f. a) What is the frequency of the gray allele f? b) What is the frequency of the green allele F? c) How many fraggles are heterozygous (Ff)?
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.
