Problem:
Imagine there are 40 birds on an island. For gene B, half of the total alleles in this population are B1 and the other half are B2. How many of each allele are present in this island population? Assume the birds are diploid. Responses 80 B1 alleles and 80 B2 alleles 80 B 1 alleles and 80 B 2 alleles 50 B1 alleles and 50 B2 alleles 50 B 1 alleles and 50 B 2 alleles 20 B1 alleles and 20 B2 alleles 20 B 1 alleles and 20 B 2 alleles 40 B1 alleles and 40 B2 alleles 40 B 1 alleles and 40 B 2 alleles Question 2 Now, imagine that 10 birds from the mainland population fly to this island and join the population. The birds from the mainland carry 100% B1 alleles. Which statements accurately describe the island population after this gene flow event occurred? Select all that apply. Responses There are now 100 total alleles of gene B on the island. There are now 100 total alleles of gene B on the island. The new frequency of the B1 allele is 0.6. The new frequency of the B 1 allele is 0.6. The new frequency of the B2 allele is 0.5. The new frequency of the B 2 allele is 0.5. Although more birds arrived, they carried alleles already present on the island, therefore allele frequencies did not change. Although more birds arrived, they carried alleles already present on the island, therefore allele frequencies did not change. There is not enough information provided to calculate the new allele frequencies. Need Assignment Help?
