Well 1, why would I pretend that I was a carbon atom. 2, I’m to tired to, 3, just no.
The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion. The correct options are D and E.
<h3>What is genetic variation?</h3>
The presence of differences in gene sequences between individual organisms of a species is referred to as genetic variation. It allows for natural selection, which is one of the primary forces driving life's evolution.

Answer: Mechanical Isolation
Explanation:
Mechanical isolation is a type of barrier that prevents the species that are closely related from mating with each other.
It is used in case of plants and animals(here beetles) in which the without compatible sex organs individual of different species will not be able to mate and produce offspring.
Thus, the correct answer is option C
