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: -Meiosis is important for creating genomic diversity in a species. It accomplishes this primarily through 2 processes: independent assortment and crossing over (recombination).

Detailed explanation-3: -One purpose of meiosis is to reduce the number of chromosomes by half. The other is to create genetic diversity. Meiosis begins like mitosis: the cell copies each chromosome. But unlike in mitosis, homologous chromosome pairs line up and exchange pieces-a process called recombination.

Detailed explanation-4: -Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell.

Detailed explanation-5: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
