The wing type of a particular species of insect is determined by a sex-linked gene with two alleles, A (which is dominant) and a. Spotted wings are recessive to plain wings. Questions A plain-winged male is crossed with a heterozygous plain-winged female. (a) (i) What proportion of male offspring of this mating should you expect to have plain wings? (ii) What proportion of female offspring should you expect to have plain wings?
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.
