Pre-adaptation may occur because a natural population carries a huge quantity of genetic variability. In diploid eukaryotes, this is a consequence of the system of sexual reproduction, where mutant alleles get partially shielded, for example, by the selective advantage of heterozygotes.daptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2.
