Population Genetics Review Problems 1 Given a population with 87 A1A1 individuals 112 A1A2 individuals and 43 A2A2 individuals calculate the genotype frequencies D H R and from these calculate the allele frequencies p q Is this population in HardyWeinberg equilibrium 2 Among reproductive adults the allele A1 comprises 373 of the alleles at the A locus the rest are the A2 allele in a population of 1 million individuals What are the expected gamete frequencies and the expected genotype frequencies of the offspring assuming that genotypes have equal fertility and there is random mating 3 Consider two populations with the same allele frequencies but different genotype frequencies Population I AUM122 AUVO A v78 Population II A 80 A v82 A v37 If these populations now are subjected to the conditions necessary for HardyWeinberg equilibrium and ignore drift which will achieve HardyWeinberg ratios rst Why 4 Given the absolute tnesses of A1A132 A1A24l A2A229 calculate the relative tnesses and the selection coef cients for each genotype Given allele frequencies of p03 q07 calculate the mean tness for the population 5 If p05 and 503 against A2A2 calculate the change in q for the next two generations and the value of p and q after two generations of selection 6 Given absolute tnesses of A1A122 A1A227 A2A225 calculate the equilibrium allele frequencies for this population 7 Calculate the equilibrium allele frequencies when the mutation rate A1 to A2 is 000041 and F001 against the recessive homozygous A2A2 genotype 8 There are two equal size populations that are both in HardyWeinberg equilibrium Population I pO4 qO6 Population II pO8 q02 What would be the difference between the observed and expected frequency of l t J g t ifthese r r 39 quot were 39 39 J into a single population 9 Given relative tnesses w1106 w12l w2204 and starting allele frequencies of p05 q05 calculate the change in p for 1 generation of selection How much has the mean tness of the population changed 10 Generate three different genotype frequencies not including the HardyWeinberg ratios that are consistent with allele frequencies of p03 and q07
