Question

in the punnett square, fill in the shaded boxes with the alleles of each parent. use b for the dominant allele (black fur) and b for the recessive allele (white fur).

Explanation:

Step1: Identify parent alleles placement

In a Punnett - square, the alleles of one parent are placed along the top row and the alleles of the other parent are placed along the left - hand column.

Step2: Fill in the alleles

Assuming both parents are heterozygous (Bb), we place the alleles of the male parent (Bb) across the top and the alleles of the female parent (Bb) down the left - hand side. So, along the top, the first box gets B and the second gets b. Along the left - hand side, the first box gets B and the second gets b.

Answer:

Top row (male alleles): B, b
Left - hand column (female alleles): B, b
