Choose the incorrect statements.
I. Sexual reproduction brings about variations and genetic recombination in genes.
II. All variations seen in organisms are due to sexual reproduction only.
III. Asexual reproduction preserves genetic information.
IV. By hybridization, only desired genes of parents are incorporated into the hybrid produced.
All variations are not due to sexual reproduction. Some variations are due to mutations. In hybridization, not only desirable genes but also undesirable genes can be incorporated.
