In sheep, white wool is dominant over spotted wool. If 10 purebred white wool sheep (TT) are crossed

Anon25 [30]

Answer:

Explanation:

This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.

In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.
