1.Consider two genes that are independent, the A gene and the B gene. Each gene has two alleles (A gene: A1 and A2, B gene: B1 and B2). The frequency of A1 allele at the A gene is 0.85, and the frequency of the B2 allele at the B gene is 0.24. What is the probability of an individual in a randomly mating population of having A1B2|A2B1 as their genotype?

2.I am studying a bed of mussels on coast of California. There are five species and the abundance of each is: 100, 500, 998, 12, and 1548. If I randomly sample the mussel bed, what is the probability I will pick the third species? 0.316

Solution

2.Probability of picking the third spicies is:

(998)/(100+500+998+12+1548)

=0.316
