Select the incorrect statement.
1 Inbreeding increases homozygosity
2 Inbreeding is essential to evolve purelines in any animal.
3 Inbreeding selects harmful recessive genes that reduce fertility and productivity
4 Inbreeding helps in accumulation of superior genes and elimination of undesirable genes
Explanation:
Inbreeding increases homozygosity and hence is useful in developing purelines. Inbreeding exposes harmful recessive genesthat are eliminated by selection. So, it helps inaccumulation of superior genes and eliminationof less desirable genes. Therefore this is selectionat each step, increase the productivity of inbredpopulation. Close and continued inbreedingusually reduces fertility and even productivity.

When breeding is between the unrelated animals, including individuals of the same breed but having no common acestors for 4-6 generations or between different breeds or different species, is called
1 Outbreeding
2 Inbreeding
3 Out crossing
4 Cross breeding
Explanation:
Outbreeding refers to the mating of unrelated animals belonging to Individuals of the same breed but having no common ancestors on either side for at least 4-6 generations(outcrossing) Individuals of the different breeds (cross-breeding) Individuals of different species (interspecific hybridisation)

During MOET, a cow is administered hormones, with FSH-like activity, to produce
1 2-8 eggs
2 8-32 eggs
3 6-8 eggs
4 16-18 eggs
Explanation:
During MOET, a cow administered hormones, with FSH- like activity, to induce follicular maturation and super ovulationinstead of one egg, which they normally yield per cycle, they produce 6-8 eggs.

Inbreeding in animal husbandry increases ____
1 Homozygosity
2 Heterozygosity
3 Inbreeding depression
4 Both 1 and 3
Explanation:
Inbreeding increases homozygosity. Continued inbreeding, especially close inbreeding, usually reduces fertility and even productivity. This is called inbreeding depression.
