A black hairy rabbit homozygous for this common trait is crossed with a white smooth rabbit. Determine the phenotype and genotype of the hybrid F1 generation. B (black coat) c (white coat) C (shaggy) c (smooth).
Given: B-black (dominant), b-white (recessive. C-furry (dominant), c-smooth (recessive). The black furry rabbit is homozygous. Hence its genotype BBCC. Thus, it forms BC gametes.
The white smooth rabbit is also homozygous. Hence her genotype is bbcc. Thus, it forms the bc gamete.
After crossing, hybrids with BbCc genotypes are formed. By phenotype: all hybrids are black and hairy. The first generation uniformity law is manifested.
