Suppose that in generation 0, the frequency of allele A1 in a population of armadillos is 0.4. In each generation, 10 percent of the individuals in that population are migrants from another population that has an allele frequency of 0.6.

a. Calculate the frequency of A1 in each of the next two generations (generations 1 and 2).

b. Is the change in allele frequency in generation 2 greater than, less than, or equal to the change in generation 1? How can you explain that answer?

A mainland population of 1000 blue iguanas have the neutral alleles A1 and A2 with frequencies of A1 = 0.50 and A2 = 0.50.

A new population of blue iguanas is founded on Lizard Island with a population size of 10 males and 15 females.The neutral alleles A1 and A2 are present in the population with frequencies of A1 = 0.30 and A2 = 0.70. Migrants begin moving from the mainland to Lizard Island at a rate of 1 migrant per generation.

1. Calculate the change in frequency (?p) of the A1 allele after one generation of migration.

2. What will the new frequency (p?) of A1 be in the island population after one generation of migration ?

Popgen 8: suppose two alleles, C and D, control flower color, CC plants have red flowers, while CD and DD plants have pink flowers. Suppose that in a population of 1000 individuals, I count 840 pink flowered plants. Assuming that the population is in Hardy- Weinberg equilibrium, what is the frequency of the allele C? Correct answer is 0.4 but dont know how to solve for it.

Popgen 9: Popgen 9: Consider a process of one-way migration from a very large population into a small population. A gene has two alleles A1 and A2. The frequency of A1 in the small population (p-small) is 0.3, and the frequency of A1 in the large population (p-large) is 0.8. Assuming a migration rate of m = 0.1, and no mutation, selection, or genetic drift, what do you expect to see in the next generation?

Popgen 14: Recall our model of one-way migration from a large mainland onto a small island. Consider two alleles A1 and A2. The frequency of allele A1 on the mainland (p-mainland) is 0.2, while the frequency of A1 on the island (p-island) is 0.8. The rate of migration from the mainland to the island per generation is 0.1. What is the expected value of p'-island, the frequency of A1 on the island after one generation?

You begin work on the genetics of shell banding patterns in a snail. A test cross indicates that mottling is controlled by two alleles (M and m) at a single locus. Individuals carrying the M allele have mottled shells, while mm snails have no mottling. You sample a population and determine that the frequency of m in the population is 0.6. Assume that the population is at HWE when answering the following questions: (i) What is the frequency of the M allele in the population? (ii) What are the expected genotype frequencies in the next generation? (iii) What are the expected frequencies of the mottled and non-mottled phenotypes in the next generation? (iv) How should the frequency of the M allele change through time
