Answer:

Selectivity in choosing a mates

Geographic barriers separating subpopulations.

Explanation:

Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.

Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.

When there is geographic separations or demarcation between individuals in a species and they are separated from other subpopulations .. They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.

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.
