Answer:

Blue whales were significantly depleted by commercial whaling activities worldwide. The latest stock assessments of blue whales include data for various stocks, including areas of the North Pacific and western North Atlantic Oceans.

Whaling killed hundreds of thousands of blue whales from the early 1900s until it became illegal in 1966. Blue whales continue to be threatened by boats, anthropogenic noise, pollution with toxic chemicals, climate change (which may affect how the population of krill), and from fishing.

How can we prevent blue whales from extinction?

Matings between individuals from the two populations of Rhagoletis produce hybrid flies that appear to be healthy and have norma

Mama L [17]

<h2>The correct answer is : C.</h2>

Explanation:

According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.
