Answer:
The correct answer is option B) "habitat isolation".
Explanation:
The two populations of ticks herein described have preference in one of two populations: either over mule deers or white-tail deers. One term that might be applied to describe these populations is habitat isolation. Habitat isolation occurs when the chances of mating between individuals of the same species are lowered because of differences in habitat preference. This is the case for the two populations of ticks, where because of differences in host preference, the ticks that feed from mule deers are isolated from the ones that feed from white-tail deers and vice-versa.
Given what we know, we can confirm that the two organisms most closely related would be the human and the gorilla.
<h3>Why are the Gorilla and Human the most closely related?</h3>
Using only the information given from the diagram, we can say that gorillas and humans are the most closely related. Although the turtle and the chicken also share the same genetic similarities in the diagram, the human and the gorilla also share physical aspects between them, making them more related than the previous group.
Therefore, given that they share genetic and physical aspects, we can confirm that the two organisms most closely related would be the human and the gorilla.

Ans.
HD (Huntington's disease) is a genetic neurological disorder that occurs due to damage and death of brain cells. it is caused by an autosomal dominant mutation in HTT (huntingtin) gene, having a trinucleotide repeat section that makes HTT protein.
The mutation leads to an increase in this nucleotide repeat count, associated with formation of altered or mutated huntingtin protein. These altered proteins show deleterious affect on brain cells and result in Huntington's disease.
Thus, the correct answer is 'option A). a mutated gene.'
