- How Can We Measure Allele Frequencies in Populations? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.arrow_forwardHow Can We Measure Allele Frequencies in Populations? What are four assumptions of the HardyWeinberg law?arrow_forwardHow Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.arrow_forward

What is the total allele frequency in both populations?arrow_forwardThere are 100 dominant homozygotes, 100 heterozygotes, and 100 recessive homozygotes in a population. How many dominant alleles and how many recessive alleles are in this population?

- Allele frequencies in a population should remain constant unless one or more factors cause those frequencies to change. What is this based on?arrow_forwardWe have used a small population (52) of consistent and known age structure, with only four possible genetic states (four alleles of one gene). What does this exercise suggest to you about the effects of a bottleneck in populations involving hundreds of genes and alleles, some of which may be very rare (frequency 0.01 or less)? In other words, what are the limitations of this model compared to real populations?arrow_forwardA particular deer population has 50 M individuals, 30 MN individuals, and 70 N individuals. What are the allele frequencies?arrow_forward
