Assume that the dominant allele for the D gene occurs at afrequency of 0.8 in a population. What percentage of thepopulation is heterozygous for the D gene, based onHardy–Weinberg equilibrium?a. 80% c. 32%b. 64% d. 20%

In achondroplastic dwarfism, an autosomal dominant disease, the gene is lethal in homozygotes. If the frequency of the normal allele is 0.99, what is the heterozygote frequency? a. 0.01 b. 0.02 c. 0.98 d. 0.99       An autosomal recessive gene is lethal in homozygotes. In a population at Hardy- Weinberg equilibrium, how many generations will it take to eliminate the gene from the population a.100 b.It will not be eliminated from the population. c.1 d.25

Assume you have a population with alleles A and a at a genetic locus. You measured the population and found 30 AA homozygotes, 100 Aa heterozygotes, and 70 aa homozygotes. What is the frequency of A and a in the population?   a. A = 0.3; a = 0.7   b. A = 0.7; a = 0.3   c. A = 0.4; a = 0.6   d. A = 0.6; a = 0.4

imagine a population evolving by genetic drift, in which the frequency of allele K is 0.2. what is the probability that at some point in the future allele K will drift to a frequency of 1.0? express your answer as a number between 0 and 1
