MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Starts with one diploid cell
A
mitosis
B
meiosis
C
both mitosis & meiosis
Explanation: 

Detailed explanation-1: -Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes.

Detailed explanation-2: -Typically, this type of cell division occurs in the body’s somatic cells. Therefore, the parent cell in mitosis starts off as diploid. Since mitotic cell division results in the formation of new cells which are clone to the parental cell, the resulting daughter cells at the end of mitosis are diploid.

Detailed explanation-3: -Meiosis is similar to mitosis in many ways, but there are a couple of important differences. First of all, even though meiosis starts with a diploid cell (a primary oocyte or primary spermatocyte), its end products are 4 haploid daughter cells, each with 23 chromosomes.

Detailed explanation-4: -Mitosis is how the cells of your body reproduce. During mitosis, a diploid parent cell (i.e. a cell with two sets of chromosomes) makes a complete copy of its DNA before splitting in two. This process produces two genetically identical daughter cells and takes place across five phases.

Detailed explanation-5: -Answer and Explanation: Meiosis begins with a single diploid cell and ends in forming four haploid cells. Meiosis begins with a diploid (2n) parent cell, splitting into four haploids (n) cells.
