Question

Two sheep are bred with the following genes:

S = dominant white wool
s = recessive spotted wool
Male = ss,Female = Ss
How many offspring have spotted wool?
A.2
B.4
C.1

Answer 1

The number of offspring with spotted wool is 2.

Step-by-step explanation:

To determine the number of offspring with spotted wool, we need to analyze the genotypes of the parents. The male sheep has the genotype ss, which means it carries two copies of the recessive spotted wool gene. The female sheep has the genotype Ss, which means it carries one copy of the dominant white wool gene and one copy of the recessive spotted wool gene. When these two sheep breed, there are four possible combinations of alleles that can be passed on to the offspring: SS, Ss, Ss, and ss. The offspring with the genotype ss will have spotted wool, so the answer is A. 2, as two offspring will have spotted wool.
