NEET BIOLOGY

Detailed explanation-1: -Somatic cells, which are most cells in the body, are diploid, meaning that the cell doubles its chromosome number to 4N during mitosis before dividing and the resulting daughter cells are 2N.

Detailed explanation-2: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-3: -The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.

Detailed explanation-4: -In this simple example, a diploid body cell contains 2n = 2 chromosomes. One chromosome came from mom and one from dad. In humans, 2n = 46, so 23 came from mom, and 23 from dad.

Detailed explanation-5: -The purpose of mitosis is to make more diploid cells. It works by copying each chromosome, and then separating the copies to different sides of the cell. That way, when the cell divides down the middle, each new cell gets its own copy of each chromosome.
