Inbreeding depression is -
1. Reduced motility and immunity due to close inbreeding
2. Decreased productivity due to mating of superior male and inferior female
3. Decrease in body mass of progeny due to continued close inbreeding
4. Reduced fertility and productivity due to continued close inbreeding
Select the incorrect statement
1. Inbreeding helps in the accumulation of superior genes and the elimination of undesirable genes
2. Inbreeding increases homozygosity
3. Inbreeding is essential to evolve purelines in any animal
4. Inbreeding selects harmful recessive genes that reduce fertility and productivity
Select the incorrect statement regarding inbreeding:
1. Inbreeding helps in elimination of deleterious alleles from the population
2. Inbreeding is necessary to evolve a pure-line in any animal
3. Continued inbreeding reduces fertility and leads to inbreeding depression.
4. Inbreeding depression cannot be overcome by out-crossing.
