Document Summary

Compare these with observed genotype frequencies: predicted genotype frequencies is calculated first by finding out the expected genotype frequencies by using p^2+2pq+q^2 a. i. p^2 measures the dominant homozygous genotype a. i. 1. p = allele frequency of one allele a. ii. 2pq measures the heterozygous genotype a. iii. q^2 measures the recessive homozygous genotype a. iii. 1. q = allele frequency of the other allele b. If the predicted genotype frequencies is equal to the observed genotype frequencies then the population is in hardy-weinberg equilibrium: list the conditions that must be met for a locus in a population to be at hardy- Weinberg equilibrium (assumptions of hardy-weinberg equilibrium theory): conditions that must be met for a locus in a population to be at hardy-weinberg. It can alter allele frequencies in populations b. ii. It can reduce genetic differences among populations b. iii. It can counteract the loss of genetic variation caused by drift b. iv.

A particular gene in a given population of individuals has two alleles, A and a. The frequency of the A allele equals the frequency of the a allele. What are the expected genotype frequencies, assuming the population is in Hardy-Weinberg equilibrium?

	AA = 0.25, Aa = 0.50, aa = 0.25
	AA = 0.5, aa = 0.5
	The answer cannot be determined because the allele frequencies are not provided.
	A = 0.5, a = 0.5

A) true B)false C) can not be determined

Which of the following evolutionary forces would be the best explanation for the genotype frequencies in the population in the above question?

A) genetic drift B) there are no evolutionary forces acting on this gene population C)assortive mating D) Overdominance E)Directional selection

If a population is at Hardy-Weinberg equilibrium, which of the following allele frequencies would yield the smallest number of heterozygotes? A)

A=0.25, B=0.75 B) A=0.75, B=0.25

C)A=0.50, B=0.50

D)A=0.10, B=0.90

Fixation occurs when one allele becomes the only allele for a gene in a population, meaning that all other alleles for that gene have been lost. True or false
