Answer:
A rabbit with Bb genotype will be black coated phenotypically
Explanation:
The question involves a single gene coding for coat color in rabbits. According to the question, the allele for black coat (B) is dominant over the allele for white coat (b). This means that black coat allele (B) will mask the phenotypic expression of the white coat allele (b) in a heterozygous state.
A rabbit with genotype, Bb is said to be heterozygous because it possesses the combination of the two different alleles (dominant and recessive). Since, the 'B' allele (black) is dominant, it will mask the expression of the 'b' allele (white). Hence, the rabbit will phenotypically appear black coated.
Alleles are the form of the gene, which codes for variant phenotypic traits of an organism. It is present on the same locus on the chromosome.
In rabbits with genotype Bb, the phenotype will be Black.
The genotype of an organism controls the phenotypic characters. In the given example, it is given that:
- B is dominant and codes for the black color.
- b is recessive and codes for the white color.
In genetics, the dominant genes are expressed in purebred or heterozygous conditions, whereas recessive is only expressed in the purebred conditions.
The cross between the black phenotype (BB or Bb) and white (bb) phenotype will give rise to progeny having either black or white color.
The genotype for bb will be white, Bb will be black, and BB will also be black.
Thus, the phenotype of the rabbit with the genotype Bb will have a black color coat.
