NEET BIOLOGY

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: -In meiosis, a cell containing the diploid number of chromosomes is converted into four cells, each having the haploid number of chromosomes. In human cells undergoing meiosis, for instance, a cell containing 46 chromosomes yields four cells, each with 23 chromosomes.

Detailed explanation-3: -Chromosomes in diploid cells are arranged in homologous pairs. The diploid chromosome number of a cell (2n) is the total number of chromosomes in a cell. In the case of humans, 2n = 46, meaning there are a total of 46 chromosomes in a diploid human cell.

Detailed explanation-4: -Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Detailed explanation-5: -Gametes are produced by a type of cell division called meiosis. How many chromosomes are in a human zygote? A gamete is a haploid sex cell (23 chromosomes-in humans), and a zygote is the rst diploid cell of a new organism (46 chromosomes-in humans).
