anygoal [31]

Answer:

Option C

Explanation:

Long term hunting has led to following  

a) Reduction in population size and hence the gene pool

b) Causation of Bottleneck effect

Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.  

Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.  

Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism

Option C is correct

valentinak56 [21]
Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
