Select the incorrect statement regarding inbreeding.

Options

  1. AInbreeding helps in the elimination of deleterious alleles from the population
  2. BInbreeding is necessary to evolve a pureline in any animal
  3. CContinued inbreeding reduces fertility and leads to inbreeding depression
  4. DInbreeding depression cannot be overcome by outcrossing

Correct answer

D. Inbreeding depression cannot be overcome by outcrossing

Step-by-step solution

The incorrect statement regarding inbreeding is the option (d). It is because continuous inbreeding among cattle causes inbreeding depression. It decreases the fertility and even productivity of an animal. It can be overcome by applying outbreeding in which mating is done between different breeds or individuals of the same breed but having no common ancestors. Outbreeding includes outcrossing, cross-breeding and interspecific hybridisation.
