Key Concepts

Sibling Mating

Sibling mating involves the reproduction between brothers and sisters or close kin that share a high proportion of genetic material. This type of inbreeding mechanism is often observed in small or isolated populations and can accelerate the accumulation of deleterious alleles.

Cousin Mating

Cousin mating is the reproductive pairing between first cousins. While less extreme than sibling mating, it still increases the likelihood of similar alleles coming together, thereby elevating the risk of inheriting genetic disorders, and is a common focus in studies of consanguinity.

Inbreeding

Inbreeding refers to the mating of individuals who are genetically related. It is a common concept in genetics and evolutionary biology, affecting the genetic diversity and fitness of populations by increasing homozygosity, which can lead to the expression of recessive traits and potential inbreeding depression.

Self-fertilization (Selfing)

Self-fertilization is a form of inbreeding where an individual organism fertilizes its own gametes. This mechanism is common in many plants and some hermaphroditic animals, and while it ensures reproduction in the absence of mates, it also reduces genetic diversity within a population.
