B. The LM and LN alleles at the MN blood group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios in progeny resulting from the following crosses:

The ABO blood group gene has three alleles, with IA and IB codominant, and i recessive. The Rh blood group gene has only two alleles, with the Rh+ phenotype (R allele) dominant over Rh–(r allele). Finally, the MN blood group gene has two codominant alleles, M and N. A child has blood types B, Rh–, and M. His mother has blood types O, Rh+, and MN. Give the genotype of the mother, and the possible genotypes of the father.

4. Short hair in rabbits is governed by a dominant gene (L) and long hair by its recessive allele (l). Black hair results from the action of the dominant genotype (B-) and brown from the recessive genotype (bb).

a). In crosses between dihybrid short, black and homozygous short, brown rabbits, what genotypic and phenotypic ratios are expected?

b). Determine the expected genotypic and phenotypic ratios in progeny from the cross LlBb x Llbb.

Hi, Can you please explain clearly. Thank you.
