If two eukaryotes participate in lateral gene transfer what will this do to the overall genetic variation of the
species?
a) nothing, the genetic variation will stay the same.
b) the genetic variation will decrease.
c) the genetic variation will increase.
d) this type of gene transfer is impossible in eukaryotes.

The correct answer would be C) The genetic variation will increase.

Horizontal or lateral gene transfer refers to the transmission of genetic material between two different genomes which is distinguished from a transfer of genetic material from parent to the offspring that is, vertical gene transfer.

For example, transformation, transduction, and conjugation result in horizontal gene transfer in bacteria.

It increases genetic variation of the population and plays important role in adaptation as well as evolution.
