Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B

Karolina [17]

Answer:

100% or 1

Explanation:

This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.

In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.
