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). male female

Explanation:

Step1: Determine possible alleles from parents

Parents can contribute either B or b alleles.

Step2: Fill top - row (male alleles)

The top - row (representing male gametes) can have B or b. Let's assume the male can contribute B and b alleles, so we can fill the top - row boxes as B and b.

Step3: Fill left - column (female alleles)

The left - column (representing female gametes) can also have B or b. Let's assume the female can contribute B and b alleles, so we fill the left - column boxes as B and b.

Step4: Fill interior boxes

For the interior boxes, we combine the alleles from the corresponding row and column. For example, the top - left interior box gets the combination of the allele from the top - row (first box) and left - column (first box). So if top - row first box is B and left - column first box is B, the interior box is BB. Similarly, if top - row second box is b and left - column first box is B, the interior box is Bb, and so on.

Answer:

Top - row (male): B, b
Left - column (female): B, b
Interior boxes (from top - left to bottom - right): BB, Bb, Bb, bb
