Which of the following best explains how genetic recombination influences evolution?
a.
the genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon
b. genetic recombination occurs only in small breeding populations and always results in the loss of favorable alleles from
the population
c.
new alleles that were not previously present within a population can only be introduced through the process of
recombination
d.
the process of genetic recombination results in only those traits that provide a reproductive advantage being passed
down to future generations,

The correct option is A. The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.

Explanation:

Recombination will lead to more possibilities for allelic combinations. This will result in increase in the number  of genetic variations for a population.. The genetic variations in a population help the organisms to better adapt to different environmental conditions. If genetic variation is low for a population, then there are more chances for the population to become extinct or endangered when disasters occur. Many ecologists blame lack of genetic variation for extinction of different species.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
