Imagine two populations of a fish species, one in the Mediterranean Sea and one in the Caribbean Sea. Now imagine two scenarios: (1) The populations breed separately, and (2) adults of both populations migrate yearly to the North Atlantic to interbreed. Which scenario would result in a greater loss of genetic diversity if the Mediterranean population were harvested to extinction? Explain your answer.

Answer: (1) The populations breed separately.

Explanation:

The genetic diversity can be define as the total number of different types of genes is present in a particular species. Genetic diversity makes the way suitable for the survival of the population of species in changing environment.

According to the given situation, if the two population breed separately then then no new genes will be added to the gene pool of the species and hence, the genetic diversity will be lost.
