Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process is completed with a full complement of chromosomes (46)?
A
Mitosis
B
Meiosis
Explanation: 

Detailed explanation-1: -When the cell divides, the copies are pulled apart, and each new cell gets one identical copy of each chromosome. This type of cell division is called mitosis, and it produces cells with a total of 46 chromosomes.

Detailed explanation-2: -At the conclusion of anaphase, each end of the cell has an identical and complete set of 46 chromosomes or 23 pairs of homologous chromosomes; they are still diploid.

Detailed explanation-3: -Therefore, meiosis results in four haploid genetically unique daughter cells, each with half the DNA of the parent cell (Figure below). In human cells, the parent cell has 46 chromosomes (23 pairs), so the cells produced by meiosis have 23 chromosomes.

Detailed explanation-4: -Diploid. A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total.
