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.
The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion.
Thus, the correct options are D and E.

Sexual reproduction<span> provides </span>genetic diversity<span> because the sperm and egg that are produced contain different combinations of </span>genes than<span> the parent organisms. ... Each resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell.</span>
<span>Both somatic and germinal mutations are contributors of evolution. Somatic mutations occur within tissues of individuals that give the said individual differing traits and characteristics. Germinal mutations occur in reproductive cells that can be passed on to offspring, altering their traits and characteristics.</span>
The best answer is A.) They can poison soil organisms, because pesticides contain chemicals that can be dangerous to plants.
