A homozygous black rabbit was crossed with a homozygous white rabbit. Determine the genotypes and phenotypes of the first generation rabbits. Will the hybrid offspring split?
Let’s designate the gene that causes the black color of rabbit fur as K. then the gene for white fur will be k.
A homozygous female rabbit with black fur will have the KK genotype and will produce the same type of K.
A homozygous rabbit with white fur will have the kk genotype. His body will be able to produce only one type of sperm – k.
The offspring obtained from crossing the described rabbits with each other will be represented by heterozygous rabbits with the Kk genotype with black fur.
No splitting will be observed in the offspring.
