The probability that an offspring of the cross shown above will have the genotype Bb is 1:2. The correct option is D.
Alleles are the variations of the gene or trait of an organism. One gene contains a variation of the same type of trait. These traits come to form the mother and the father of the offspring.
They are of two types, the dominating and recessive. The dominating allele is denoted by a capital letter and the recessive gene is denoted by a small letter.
Here, the dominating allele is brown fur, B and the recessive allele is b, white fur. When crossing over happens, there is the probability of having the genotype Bb is 2:4 which will be 1:2.
Thus, the correct option is D. 1:2.
