Detailed explanation-1: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.
Detailed explanation-2: -Each daughter cell has half the number of chromosomes as compared to their parents (one copy of each chromosome). The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1.
Detailed explanation-3: -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-4: -In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes.
