WebGenetic load will tend to be lower in species (populations) in which inbreeding has been common in the past (e.g. species with small population sizes) — simply because past inbreeding will have exposed harmful recessives to selection, and thus reduced their frequency, or eliminated them "purging inbreeding depression". WebThis trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait!
