olya-2409 [2.1K]

Answer:

This outcome in a hybrid zone is known as <u><em>fusion</em></u>.

Explanation:

In the field of biology, hybrid zone can be described as the area where closely-related species can interbreed and produce hybrid organisms. Reinforcement can be described as the phenomenon by which a hybrid zone develops between full species barriers. Hybrid speciation can be described as the phenomenon by which a new species forms as the direct result of mating between members of two existing species.

How could a geneticist best explain the dominance of blood type B in the island population?


Multiple choices;

A. Random mutations have occurred in the island population.

B. Genetic drift has reduced the frequency of type A individuals.

C. Natural selection has only occurred in the mainland population.

D. Environmental conditions on the island are less favorable for type B individuals.


Answer;

B. Genetic drift has reduced the frequency of type A individuals.


Explanation;
