Animal Husbandry – Breeding: Inbreeding
-
Which one of the following is NOT an advantage of inbreeding?A It decreases the productivity of inbred population, after continuous inbreeding.B It decreases homozygosity.C It exposes harmful recessive genes that are eliminated by selection.D Elimination of less desirable genes and accumulation of superior genes takes place due to it
Continued inbreeding reduces fertility and productivity (inbreeding depression), which is a disadvantage.
The selection of desirable genes at each step increases the productivity of inbred population. However, continued inbreeding, especially close inbreeding, usually reduces fertility and even productivity. Hence referred as inbreeding depression. -
Select the incorrect statement:A Inbreeding increases homozygosityB Inbreeding is essential to evolve purelines in any animalC Inbreeding selects harmful recessive genes that reduce fertility and productivityD Inbreeding helps in accumulation of superior genes elimination of undesirable genes
