Using the information provided in question #44, what would be the phenotype if the offspring is Bb?
Correct answer
A
Rationale
In genetics, when discussing the phenotype of an offspring with a genotype of Bb, the dominant trait 'Black' would be expressed. In this case, the dominant allele 'B' leads to the expression of the black color, overriding the recessive allele 'b,' which would signify tan. Therefore, the correct answer is A, 'Black.' The dominant allele 'B' in the genotype Bb expresses the black color, as it is dominant over the recessive allele 'b.' Hence, the phenotype of the offspring with the genotype Bb would be 'Black.'
