Inbreeding science definition
Inbreeding increases homozygosity, which can increase the chances of the expression of deleterious or beneficial recessive alleles and therefore has the potential to either decrease or increase the fitness of the offspring. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes.

WebInbreeding is the mating of organisms closely related by ancestry. It goes against the biological aim of mating, which is the shuffling of DNA. Human DNA is bundled into 23 pairs of chromosomes, within each chromosome there are hundreds of thousands of genes and what’s more, each gene has two copies known as alleles. WebInbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically.
