|
|
|
consistent genetic makeup of all gametes
|
|
|
larger daughter cells
|
|
|
two gametes for every original parent cell
|
|
|
cells with half the number of chromosomes
|
Detailed explanation-1: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Detailed explanation-2: -As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
Detailed explanation-3: -In mitosis, homologous chromosomes (a pair of maternal and paternal chromosomes) in diploid cells behave independently upon segregation, whereas in meiosis, homologous chromosomes are paired and a part of them are physically connected by chiasmata.
