The probability of a homozygous dominant (BB) offspring resulting from a cross between two parents with the genotype Bb can be calculated using a Punnett square.
When cross a Bb parent with another Bb parent, the possible genotypes of the offspring are BB, Bb, Bb, and bb.
Therefore, the probability of getting a BB offspring is 1/4 or 0.25.
Therefore, the correct answer is C) 1/4.
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 two parents with the genotype Bb.
