The answer is A. Meiosis: It increases genetic variation, which helps ensure the species will survive.

Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.

Two organisms, with the genotypes FFEe and FfEE, are mated. Assuming independent assortment of the F/f and E/e genes: 1) Provide

IgorC [24]

Answer:

<h2> FFEE, FfEE, FFEe, and FfEe</h2><h2> All the progeny show same 1/4 or 25% probability.</h2>

Explanation:

Given; parents are with genotype FFFe and FfEE

F/f and E/e are showing independent assortment,

1. Genotype of all possible offspring are;

gamete from parent FFEe are; FE and Fe ,

gamete from parent FfEE are; FE and fE.

So genotype of offspring are: FFEE, FfEE, FFEe, and FfEe

2. All the progeny show same 1/4 or 25% probability.
