|
Unlike mitotic cells, meiotic cells undergo a single division to halve their chromosome number, after which they undergo crossing over to restore their diploid state.
|
|
|
Unlike mitotic cells, meiotic cells undergo multiple divisions to produce an effectively unlimited array of daughter cells which are genetically identical to the parent cells.
|
|
|
Unlike mitotic cells, meiotic cells undergo pairing of homologous chromosomes, allowing centromeres to remain intact throughout both cellular divisions.
|
|
|
Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.

Detailed explanation-1: -Answer and Explanation: The biggest distinguishing feature between mitosis and meiosis is the end result. Mitosis produces two daughter cells that are genetically identical to the original cell, whereas meiosis produces four daughter cells that are genetically different.
Detailed explanation-2: -Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
Detailed explanation-3: -Which statement describes a process that takes place in meiosis but not mitosis? Homologous chromosomes pair up.
