- Why is genetic variability necessary in a population? What can happen if genetic variability is reduced?What other factors besides random mating are necessary for a population for HW equilibrium frequencies of alleles and genotypes to be present?Does this model fit the idea that reproductive isolation can evolve in allopatry as just a byproduct of adaptation of each population to different environments? Why or why not?
- If the frequency of a dominant allele “B” in a population is 80%, and assuming genetic equilibrium in this population, what percentage of the offspring in the next generation could be expected to have the heterozygous genotype?How 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.How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
- 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.In a population of 2000 ladybugs at equilibrium, there are 1120 ladybugs with eight spots (SS), 30 with six spots (Ss), and 850 with four spots (ss).
