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.
Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
Answer: Polygenic inheritance
Explanation:
Polygenic inheritance is a phenomenon shown by a trait that is controlled by many genes residing at different loci.
Thus, the expression of the trait is the total effect of all the genes controlling it. Skin colour and height in humans are examples of such traits.
B. the last phosphate group has a lot of energy stored in the bond that connects it to the other two phosphates.
