You measure the effects of a single allele (Y) on fitness in two populations of spiders, Population A and Population B. Population A lives near agricultural fields where pesticide is sprayed regularly. The average excess of fitness of the Y allele (ay) in Population A is 1.0, and the average fitness of the population (w) is 1.O. Population B lives in a remote forest and are never exposed to pesticides. The average excess of fitness of the Y allele (ay) in Population B is 1.8 and the average fitness of the population (w) is 1.0. a) In which mosquito population is the frequency of the Y allele going to change faster? [ Select ] b) What do vou predict will bannen to the freauency of the Y allele (nY) in Population R?

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.
