Question

In rabbits, black fur is dominant to white fur. As a rabbit breeder, you crossed a BB male with a Bb female, please complete the Punnett square for the possible genotypes of the offspring. Then complete, the percent chance for the phenotypes of the offspring.

***Please follow all Punnett square rules to complete this question.

Answer 1

When crossing a BB male rabbit with a Bb female, the Punnett square yields all offspring with genotypes expressing black fur, resulting in 100% black-furred rabbits.

Step-by-step explanation:

In the context of rabbit coat color, black fur is dominant to white fur. To determine the possible genotypes of the offspring from a BB male and a Bb female rabbit, we construct a Punnett square with the male's alleles (B,B) along the top and the female's alleles (B,b) down the side.

The resulting genotypes in the Punnett square would be:

• Top left box: BB (male B, female B)
• Top right box: BB (male B, female B)
• Bottom left box: Bb (male B, female b)
• Bottom right box: Bb (male B, female b)

The phenotype percentages for the offspring based on these genotypes would be 100% black fur, as both BB and Bb genotypes express the dominant black fur phenotype.
