Which claim below accurately explains how the process of meiosis results in genetic variation?

Below are the options:

Having two phases of meiosis allow for more unique cells to be produced.

Meiosis is a form of asexual reproduction which leads to more genetic variation.

Meiosis produces 4 haploid daughter cells which all contain identical DNA segments.

Crossing over during metaphase allows segments of DNA from 2 parents to SWAP and produce non-identical haploid cells.

The answer Meiosis is a form of asexual reproduction which leads to more genetic variation

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
