In a certain species of animals, black fur (B) is dominant over brown
fur (b). Predict the genotype and phenotype of the offspring, when both
parents are ?Bb? or have heterozygous black fur.

Dear Student,

As black fur(B) is dominant over brown fur(b), therefore the cross obtained is as follows:

Bb X Bb
On crossing the two the progeny obtained are:
• Genotype: BB  and Phenotype:Black fur
• Genotype :Bb And Phenotype: Black fur
• Genotype:Bb and Phenotype: Black fur
• Genotype :bb and Phenotype: Brown fur
