8. In rabbits, the allele for black fur, B is dominant over the allele for brown fur b. Calculate the probability of a homozygous dominant (BB) offspring resulting from a cross between t arents with the genotype Bb. 50% 25% 100% 75% 0%

To calculate the probability of a homozygous dominant (BB) offspring resulting from a cross between parents with the genotype Bb, we can use a Punnett square.A Punnett square is a diagram that shows the possible combinations of alleles that can occur in the offspring. In this case, we have two parents with the genotype Bb.The Punnett square for this cross would look like this:| | B | b ||---|---|---|| B | BB | Bb || b | Bb | bb |From the Punnett square, we can see that there is one BB combination out of the four possible combinations. Therefore, the probability of a homozygous dominant (BB) offspring resulting from this cross is 1 out of 4, or 25%.So, the correct answer is .
