Use the information below to answer questions 3-6. There may be a number of possible alleles for a given gene within a population. In a multiple allele system the dominance relationships between the various alleles must be considered. One of the more familiar examples of a multiple allelic system is that of human ABO blood types. The gene involved codes for a protein on the outside of red bloods cells. Three alleles (IA, IB and i) determine whether the protein is present or absent and the form of the protein present.  The A and B alleles code for the A and B forms of the protein and are co-dominant to each other. The O allele (i) codes for no protein and is recessive to both A and B alleles. This means there are four possible blood types (A, AB, B, and O). Show the possible genotypes and phenotypes of the offspring from a cross between a homozygous male with type A blood and a homozygous female with type B blood.

In a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.
