<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
An important tool of genetic engineering is recombinant DNA, which is DNA altered by the incorporation of genes from a different organism.
The modification and manipulation of an organism's genes through technology are known as genetic engineering, often referred to as genetic modification or genetic manipulation. It is a collection of technologies used to alter cells' genetic make-up, including the movement of genes between and within species to create better or entirely new organisms.
Recombinant DNA techniques are used to isolate and copy the genetic material of interest, while artificial DNA synthesis is used to create new DNA. Paul Berg combined DNA from the lambda virus and the SV40 monkey virus in 1972 to create the first recombinant DNA molecule.

Its called adaption when an animal changes itself to be able to survive
The answer is : C. Gravity
The Gravitional forces that the stars and planet have are different from one another. The difference in gravities All the stars and planets in our solar system create an effect in which the stars and planets are pulling each other according the force of their gravity, which create our current orbits in the syste
