In rabbits the dominant allele B produces a black coat color and the recessive genotype bb produces a brown coat. Body fat color in rabbits is white if a dominant allele Y is present and yellow if the genotype is yy. Assume the mating between rabbits with the following genotypes : BBYY x bbyy produces BbYy Calculate the recombination frequency if the BbYy offspring are mated back to brown rabbits having yellow fat bbyy and the following ratio of phenotypes is observed: Coat color Fat color # Observed Black White 125 Black Yellow 75 Brown White 85 Brown Yellow 115
