The genotype of the offspring can be determined by combining the alleles from the parents.
When a heterozygous black rabbit (Bb) is crossed with a homozygous white rabbit (bb), the possible outcomes of the offspring's genotypes are as follows:
- 50% of the offspring will inherit the allele B from the heterozygous black rabbit and the allele b from the white rabbit, resulting in the genotype Bb.
- The other 50% of the offspring will inherit the allele b from both parents, resulting in the genotype bb.
Therefore, the genotypes of the offspring would be:
- 50% Bb
- 50% bb
The phenotype of the offspring can be determined based on their genotypes.
In rabbits, the B allele represents black color, while the b allele represents white color.
Considering the genotypes of the offspring from the previous calculation, the corresponding phenotypes would be:
- 50% of the offspring with the genotype Bb will express the black color phenotype.
- The remaining 50% of the offspring with the genotype bb will express the white color phenotype.
Therefore, the phenotypes of the offspring would be:
- 50% black
- 50% white.
