Answer 1

The correct answer is: E) Recombinants may have combinations of traits that are favored by natural selection.

Recombination that occurs during the meiosis by the process of crossing over creates variability (recombinants differ from the parents). Natural selection acts on variations-differences in phenotype that can be formed during recombination. If newly formed trait contribute more to survival and reproduction (individuals with that variant survive more than individuals with other variant), natural selection will favor that trait.
