Answer

Inbreeding Outbreeding
Inbreeding refers to the mating between closely rated individuals within same breed for 4-6 generation. It refers to breeding of unrelated animals either of the same breeds but do not have common ancestor or of between different breeds (cross-breeding) or even different species. (interspecific hybridization)
INBREEDING:
  • Advantage of inbreeding: It develops homozygous pureline in an animal.thus, it increases homozygosity to evolve a pureline in any animal.
  • Disadvantage of inbreeding: Continued inbreeding reduces fertility and even yield, leading to a condition called inbreeding depression.
OUTBREEDING:
  • Advantage of outbreeding: It produces offspring having desirable features of both parents.
  • Disadvantage of outbreeding: It may produce infertile hybrid offspring.
