and the last one 2, mitochondria.

Alleles that are neutral with respect to fitness may fluctuate in frequency
due to chance events.
<h3>What are Neutral alleles?</h3>
These are the gene variant in which natural selection doesn't affect the
spread and mostly aren't inherited.
In cases where they are inherited, they will either be lost or will replace all
other alleles of the gene as a result of chance events and not because of
natural selection.
