Problem 6Short hair in rabbits is governed by a dominant gene (L) and long hair by its recessive allele (I).Black hair results from the action of the dominant genotype (B_) and brown hair from the recessivegenotype (bb).a. Construct a Punnet square representing a cross between a dihybrid short, black, and homozygousshort, brown rabbits. What genotypic and phenotypic ratios are expected among their progeny?b. Determine the expected genotypic and phenotypic ratios in progeny from the cross LLBB xLlbb.c. From crosses between LIBB and LIBB,c.1 What is the expected phenotypic ratio among the progenies?с.c.2 What progeny of the Fi genotypes breed true (i.e., what percentage is of homozygousgenotypes)?c.3 What percentage of the F1 genotypes is heterozygous for only one pair of genes?c.4 What percentage of the F1 genotypes is heterozygous at both loci?c.5 What percentage of the F1 genotypes could be used for testeross purposes (i.c. homozygousdouble recessive)?c.6 What percentage of the F1 genotypes could be used for testeross purposes at the B locus (i.e.,homozygous recessive bb)?c.7 What percentage of all short haired Fi individuals is expected to be brown?c.8 What percentage of all black F1 individuals will breed true for both black and short hair?
