Answer:

The correct option is (D).Genetic drift is otherwise known as the Sewall Wright effect or allelic drift and is defined as the change in the allelic frequency of a given population that results due to random sampling .

Explanation:

Genetic drift refers to a phenomenon that is characterized by the change in the allelic frequency of a given population. It results in the disappearance of the gene variants that eventually leads to a reduction in the genetic variation. Occurrence of chance phenomena like emigration and immigration and independent selection eventually leads to genetic drift. This leads to the increment in the homozygosity as the changes in the associated allelic frequency does not move in the optimum predefined direction. The major driving forces is the genetic mutation or migration apart from random selection. The increased frequency and the fixation of rare alleles also occur due to genetic drift.

In McMillen and Austin’s research (1971), participants who had lied were more likely to volunteer a large amount of time.

Explanation:

The research work conducted by Mcmillen and Austin in the year 1971, included  college students as participants of the research. In this process they are asked to perform a small test of intelligence. One portion of them was asked to cheat and lie and the rest were left not to cheat.

After finishing the test, the participants were asked to help the administrator to conduct the next round of test for other slot of participants. It was seen that the students who did not lie or cheat, helped them in their work for about 2 minutes. But students, who did lie, stayed and helped for 53 minutes.

Researchers create a recombinant DNA molecule in which the coding sequence for GFP is inserted downstream of the enhancer/promot
Stolb23 [73]

Answer:

-Reporter gene.

Explanation:

A reporter gene can be defined as a gene, which is used as an indicator to check uptake or expression of gene by a cell or organism. It is attached to a regulatory sequence of a different gene of interest in cell culture, bacteria, plants, or animals by the researchers and used to confer its expression in that organism or cell.

Gene for GFP (green fluorescent protein) is an example of reporter gene, due to which cells that express gene of interest emit green color under blue light.

As in given experiment, target gene (gene for rhodopsin) is attached with gene for GFP, it represents an example of reporter gene.

Thus, the correct answer is 'reporter gene.'
