Breeding Related Alleles Genetic Individuals Define Outbreeding Explain

Outbreeding, the breeding of distantly related organisms, introduces new alleles, increases genetic diversity, and reduces the likelihood of genetic disorders.

L'outbreeding, la reproduction d'organismes peu apparentés, introduit de nouveaux allèles, augmente la diversité génétique et réduit la probabilité de troubles génétiques.

Front Define outbreeding, explain its importance for inbred/small populations.
Back Outbreeding - breeding of distantly related organisms
  • Introduces new alleles and genes into gene pool, increasing genetic diversity
  • Offspring less likely to have homozygous recessive alleles & genetic disorders
  • Stops individuals breeding with closely related individuals - larger population to breed with
