A third way that gene duplicates arise is by retrotransposition.

Here the messenger RNA from a gene is reverse-transcribed to DNA, which is then integrated into the genome.

Inbreeding

Preferential mating between related individuals.

Inbreeding is more likely to take place in nature when population size becomes very small, and the number of mates is limited.
