WebInbreeding reduces survival and reproduction (i.e. it causes inbreeding depression), and thereby increases extinction risk. Inbreeding depression is due to increased homozygosity for harmful alleles and at loci exhibiting heterozygote advantage. Webif you are asking whether inbreeding increases homozygosity, the answer is yes because that is how we breed domestic animals to have the genetic characteristics we want. The problem is that inbreeding also increase the likelihood that there is homozygosity of deleterious alleles; those that cause disease or may result in death. how to setup remote printing notice philgeps.gov.ph

Inbreeding increases homozygosity

Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. 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.
