Twenty snakes with the Aa genotype migrated to a population of 80 snakes of the same species with the AA genotype to form a new population. Assuming that the new population is now "ideal" (under genetic equilibrium) and remains "ideal" for

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. Which of the following statements is true based on the information you have on these populations?

Small populations of a diminutive rodent, each with 100 individuals, live on two small neighboring islands, Rack and Oon. The Rack population is fixed for the A allele at the Agility gene; the Oon population is fixed for the a allele at the Agility gene. Ten individuals from Rack get carried on a drifting fallen tree trunk to Oon.  Assuming the drifting individuals arrived at the start of the breeding season and that the rodents breed every year and die once they’ve raised their offspring and assuming HWE, what is the genotype frequency of AA in the Oon population the year after the accidental migration event? Please round your answer to the nearest hundredth place (for example, 0.42 or 0.89).

A population of beetles exhibits two phenotypes: red and blue. The genotypes RR and Rr result in red coloration and the genotype rr results in blue coloration. The alleles are equally prevalent (i.e. both frequencies are 0.5). A new predator is introduced and preferentially feeds on blue beetles. What do you expect to happen to the allele frequencies over time? The frequency of the rallele is expected to increase because of predation pressure. O The frequency of the Rallele is expected to increase because of predation pressure. There is not enough information to predict what will occur. O There will be no change because of the Hardy-Weinberg equilbrium.

The following table provides phenotypic data for a population of mammoths living in cold environments based on fossil and DNA evidence. Based on this data and your knowledge of natural selection, which explanation best explains the trends seen in the data? Individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offspring.   Individuals within this population of mammoths tend to only mate with individuals that have thick fur.   This population of mammoths appear to be in Hardy-Weinberg equilibrium since no allele frequencies are changing over time.   Individuals with thick fur migrated into the population of mammoths, increasing the proportion of these individuals.

Brown fur helps unicorns blend into their environment better than white fur. Therefore, brown furred unicorns are more likely to survive predators and hunters compared to white furred unicorns. If fur colour is a heritable trait, how would the population change over time? Describe how the proportion of individuals with brown versus white fur would change over time, if at all. What process is occurring in the population?

Discuss, using relevant examples, the following factors that affect Hardy-Weinberg equilibrium and thus shape diversity in a population: i) Natural selection, ii) Genetic drift; and iii) Migration

The frequency of two alleles in a gene pool is 0.19 (A) and .81 (a). Assume hardy-Weinberg equilibrium Calculate the percentage of heterozygous individuals in the population Calculate the percentage of homozygous recessives in the population

In garden pea plants, round seeds (R) are dominant to wrinkled seeds (r). In an ideal  pea plant population exhibiting Hardy–Weinberg equilibrium, 35 pea plants out  of 146 have wrinkled seeds.  Calculate the frequency of homozygous round pea plants in the population.
