Question

based on the genotypes, fill in the table to the right with the predicted percentage (0%, 25%, 50%, 75%, or 100%) of offspring for each phenotype, black or white fur. male bb female bb

Explanation:

Step1: Analyze the Punnett - square results

The Punnett - square shows the genotypes of the offspring: 1 BB, 2 Bb, and 1 bb.

Step2: Determine the phenotypes

Since B is the dominant allele for black fur and b is the recessive allele for white fur, BB and Bb genotypes result in black - fur phenotype, and bb results in white - fur phenotype.

Step3: Calculate the percentages

There are 3 genotypes (BB, Bb, Bb) out of 4 that result in black fur, so the percentage of black - fur offspring is $\frac{3}{4}\times100\% = 75\%$. There is 1 genotype (bb) out of 4 that results in white fur, so the percentage of white - fur offspring is $\frac{1}{4}\times100\% = 25\%$.

Answer:

Black Fur: 75%
White Fur: 25%
