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.

Answer:
<h2>
Cockroaches are generalized insects with few special adaptations, and may be among the most primitive living Neopteran insects. They have a relatively small head and a broad, flattened body, and most species are reddish-brown to dark brown. They have large compound eyes, two ocelli, and long, flexible antennae.</h2>
three pairs
Thorax. On the thorax, all cockroaches have three pairs of legs. Adults of most of the domestic species have two pairs of wings, although one species, the oriental cockroach, has poorly- developed wings in both sexes.
ok so no problem i’ll is going on the same page as ttyy and
Answer: Option B - There are more than four genes that determine this trait.
Explanation:
The tobacco plant species have its leaf colour with characteristics that changes gradually over a range of values, which refers to continuous variation.
Note that continuous variation keep expressing gene variants in successive generations of the tobacco plants, that differs from the parents. So, there are MORE THAN four genes controling the expression of varying phenotypes in the leaves
