You observe that the frequency of an allele at the YAPPY gene appears to be at a stable equilibrium (p* = 0.5) in a finite but extremely large population not experiencing mutation. You note that the heterozygotes for this gene tend to have more offspring because they survive to a greater degree than either homozygous genotype. Which of the following term best describes what is happening? A. Mutational equilibrium B. Hardy-Weinberg Equilibrium C. Wright-Fisher population D. Underdominance E. Overdominance You...

The Hardy–Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met. Write Yes or No for the conditions that must be met from the provided statements.                        Mutations are exponentially occurring.                        All members of the population breed.                        Everyone produces the same number of offspring.                       ...

The frequency of a recessive allele q in an island population is 0.8 and the frequency of allele q in a mainland population is 0.3. One season, some individuals from the island migrate to the mainland. After this migration, 20% of the mainland population consists of migrants from the island. What will be the frequency of allele q in the mainland population in the next generation? a) 0.4 b) 0.5 c) 0.1 d) 0 e) 0.6

You are studying two isolated populations of birds living on two different islands. In particular, you are interested in studying two different traits in these birds: beak size and feather color. Beak size is determined by a single gene exhibiting incomplete dominance. Birds with 2 copies of the A allele (genotype AA) have large beaks, birds with 1 copy of the A allele (genotype Aa) have medium beaks, and birds with no copies of the A allele (genotype aa) have...

You are doing a project on microevolution in a plant population. You observe a population of 100 plants, 25 red, 45 pink and 30 white. You return the next spring to find that the population is now made of 200 plants composed of 50 red, 90 pink, and 60 white flowers. Which conclusion would be most accurate? A. This population is not evolving because there are too few offspring in the 2nd generation. B. This population is evolving because there...

You collect several thousand Drosophila melanogaster individuals from the UCD campus. You take 1000 flies, establish a population in the laboratory and maintain it at a size of 1000 each generation. You then establish from the remaining flies a series of replicated populations of size 10, 100, 200, and 500 and maintain each at the starting size (10, 100, 200, 500) for several generations. After some time you sequence each lab population. a. If one plotted for each lab population,...

Deleterious recessive alleles on the sex chromosomes that cause incompatibility between two species will not be masked in the heterogametic sex, but will be masked in the homogametic sex. B. New, deleterious combinations of alleles at two or more autosomal loci are present in hybrids, and those deleterious combinations of alleles do not occur in the species that gave rise to those hybrids. C. Random fluctuation of...
