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?
A male child with type O blood has parents with type A blood and type B blood. Explain how this could happen if his parents have different phenotypes than him. Show at least one punnet square showing the evidence of how this could work.
In a type of cattle white hair color is dominant so is brown color. When you get the heterozygous condition both hairs are present. What would be the genotypic and phenotypic ratios produced in the f1 generation if both bull and cow of p generation are heterozygous?
A type of flower has the genotype Rr and produces a pink flower, rr genotype produces a white flower, and RR produces a red flower. What would be the f1 generation phenotypes if you crossed pink flower with a white flower? What is the the resulting genotypic ratio?
