- 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.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.In a population of 123 individuals, a locus has two alleles: E and e. If 30 individuals have the ee genotype, and the locus is at Hardy-Weinberg equilibrium, what is the frequency of the EE genotype? Round your answer to the second decimal place.
- Consider the B locus which has two alleles in a population: B and b. Researchers examined the genotypes several individuals for this locus and obtained the following numbers B/B: 302individuals B/b: 56individuals b/b: 17individuals If the B locus is at Hardy-Weinberg equilibrium, what would the expected number of individuals with the Bb genotype? Round your answer to the closest full number.In a population of 527 individuals, a locus has two alleles: T and t. If 148 individuals have the tt genotype, and the locus is at Hardy-Weinberg equilibrium, what is the frequency of the TT genotype? Round your answer to the second decimal place.Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations. Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations.

- In a population of cats, the phenotypic frequency of black cats is 91%, and the phenotypic frequency of white cats is 9%. Assuming that black (B) is dominant and white (b) is recessive, identify the appropriate frequency for each of the following for a population in Hardy-Weinberg equilibrium. Match each frequency with the correct value. Allele Frequency of b Allele frequency of B genotype frequency of BB Genotype frequency of BbIn a population with two alleles at the R locus (R and r), the frequency of the genotype rr is 0.23.
