Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process is necessary for sexual reproduction but not for asexual reproduction?
A
production of new cells
B
division of cells
C
meiosis
D
copying of genetic material
Explanation: 

Detailed explanation-1: -Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes (eggs and sperm).

Detailed explanation-2: -Only sexually reproductive organisms utilize meiosis. The role of the process is to produce sex cells and to repair genetic defects in germ line cells (the sex cells). Both sexual and asexual organisms go through the process of mitosis.

Detailed explanation-3: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-4: -Only one parent cell is required to produce another exact copy. Therefore asexual reproduction does not involve fertilization or meiosis. Sexual reproduction involves the fusion of two gametes during fertilization and the formation of haploid (half the chromosome number) gametes by meiosis.

Detailed explanation-5: -Mitosis is the mechanism of asexual reproduction. Meiosis provides the variation that sexual reproduction requires.
