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) InbreedingThis question was posed to me in quiz.My enquiry is from Animal Breeding topic in chapter Strategies for Enhancement in Food Production of Biology – Class 12
Answer» The CORRECT OPTION is (d) Inbreeding Explanation: 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.
