Question

Which of the following type of animals breeding is used to develop a pure line in any animal?

• A. Outcrossing
• B. Crossbreeding
• C. Hybridisation
• D. Inbreeding

Answer 1

Answer:

D. Inbreeding

• Inbreeding increases homozygosity, thus inbreeding is necessary if we want to evolve a pure line in any animal.

• Inbreeding also exposes harmful recessive genes that are eliminated by selection.

• It also helps in the accumulation of superior genes and the elimination of less desirable genes.
