10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals
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.
1) 10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals.
a) What is the frequency of each genotype in the population?
b) What is the frequency of the A allele?
c) What is the frequency of the B allele?
d) If the next generation contains 25,000 individuals, how many would have blood type BB, assuming the population is in Hardy-Weinberg Equilibrium?
