The heterozygous recessive genotype

(a) What is the selection coefficient for the heterozygous recessive genotype? Individuals that are homozygous recessive for a particular locus produce viable offspring at only 95% of the rate that heterozygous or homozygous dominant individuals do.

(b) What is the selection coefficient for the other genotypes? allele?

(c) Assuming allele frequencies of A1-0.78 and A2-0.22, what is the average excess of the A1
