WebbIn human beings if inbreeding continued over a number of generations, it would results in increasing homozygosity, but somewhat slowly. Inbreeding Depression: In a heterozygote, the inbreeding increases the probability of homozygosity of deleterious recessive alleles in an inbred population. WebbTheir well-documented settlements, internal migrations, and natural increase over four centuries in relative isolation (geographic, linguistic, etc.) contain important evidence of social transmission of demographic behavior that contributed to effective family size and population structure.

In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
