Previous Years Questions
1. Select the incorrect statement. [NEET-2019]
(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
Sol. Answer (3)
Inbreeding exposes harmful recessive genes that are eliminated by selection. It also helps in accumulation of
superior genes and elimination of less desirable genes. Therefore this is selection at each step, increase the
productivity of inbred population. Close and continued inbreeding usually reduces fertility and even productivity.
2. Homozygous purelines in cattle can be obtained by
