Given a single genetic locus with two alleles: A1, which occurs at a frequency 0.75, and A2, which occurs at a frequency of 0.25, how may individuals of genotype A2A2 do you expect in a population of 600 individuals at Hardy-Weinberg equilibrium?

In a bird species, the shape of the beak is encoded by a locus with two 2 co-dominant alleles Na and Nz. Na gives long beak in double dose, while individuals who are homozygous for Nz have short beak. In a population, the following genotype frequencies were observed: Na Na = 0.5 Na Nz = 0.3 Nz Nz = 0.2 a) Assume a total of 600 individuals in the population.

Assume that the ability or inability to fold the tongue is controlled by a single locus with two alleles: the ability to fold the tongue is dominant and controlled by A allele, while the inability to fold the tongue is a recessive trait controlled by the recessive allele, a. A class of 100 students was asked if they could fold their tongues. Out of all the students in the class, 25 couldn’t fold their tongues while the remaining 75 could....

A hypothetical population ofcats has two alleles, TL and TS, for a gene that codes for tail length. The allele frequency of TL is 0.7 and the allele frequency of TS is 0.3. TLTL individuals have long tails. TLTS individuals have medium tails. TSTS individuals have short tails. The equation for Hardy-Weinberg equilibrium states that at a locus with two alleles, as in this cat population, the three genotypes will occur in specific proportions, described by the equation p2 +...
