What are the advantages of inbreeding?

Inbreeding refers to the mating of closely related animals of the same breed. Inbreeding is done to develop purelines. It increases the homozygosity and helps in the accumulation of superior genes. Inbreeding also helps in eliminating less desirable genes.

Why do people avoid incest?

Incest avoidance is considered a evolutionary mechanism to avoid undesirable alleles and phenotypes from remaining in the population (Pusey, 1990). There are many mechanisms for incest avoidance, both social and biological, including sex-based dispersal, MHC haplotypes, and olfactory cues.

How did early humans avoid incest?

The results suggest that people deliberately sought partners beyond their immediate family, and that they were probably connected to a wider network of groups from within which mates were chosen, in order to avoid becoming inbred.
