A. Many traits (phenotypes), like eye color, are controlled by multiple genes. If eye color were controlled by the number of genes indicated below, how many possible genotype combinations would there be in the following scenarios?
1. 5 Genes:
2. 10 Genes:
3. 20 Genes:
B. Assume each gene has only two alleles that do not mutate or change. How many possible genotypes are there?
