Detailed explanation-1: -Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

Detailed explanation-2: -During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.

Detailed explanation-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-4: -In sexually reproducing organisms, however, genetically variable cells are produced by a process of cell division called meiosis. These genetically variable cells, often referred to as gametes, ultimately can pair to form a new, genetically variable offspring.

Detailed explanation-5: -During meiosis I, the random orientation of the maternal and paternal chromosomes can lead to variation. The exchange of genetic information between homologous chromosomes also induces variation. The random orientation of sister chromatids in meiosis II also generates genetic variation.
