Question

Now let’s examine the effect of migration out of a population. The starting population of 1000 individuals is below:

Genotype                                            # of individuals

AA                                                      350

Aa                                                       400

aa                                                        250

1. What is the frequency of the A allele in the above population?

1. 0.55
2. 0.45
3. 0.35
4. 0.25

2. What is the frequency of the heterozygotes in the above population?

1. 0.50
2. 0.40
3. 0.30
4. 0.60

Now 50 individuals of the AA genotype and 50 individuals of the aa genotype leave the population. For this starting population:

3. What will now be the post-migration frequency of the aa individuals remaining in the original (starting) population?

1. 0.35
2. 0.22
3. 0.20
4. 0.12

4. What will now be the post-migration frequency of the A allele in the remaining population?        

1. 0.70
2. 0.56
3. 0.40
4. 0. 31
