In a sub species of Sunfish dorsal spines are controlled by number of dominant alleles in two contributing pair of allelels (A and B). A fish with four spines in the dorsal fin is AABB while a fish with all recessive alleles would have the genotype aabb. What would be the offspring of a fish who had a heterozygous genotype with another fish that had one dominant A allele and all the other alleles were recessive? What is % chance of having a 0 spined dorsal fish in the f1 generation? What is % chance of having offspring with 4 spines in their dorsal fin?
