EVERYDAY SCIENCE

Detailed explanation-1: -Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total. Chromosomes are made up of long strands of DNA, which contain all the body’s genes.

Detailed explanation-2: -The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female. Females have two X chromosomes, while males have one X and one Y chromosome.

Detailed explanation-3: -Every human cell has 23 pairs of chromosomes for a total of 46 (aside from sperm and egg cells, which each contain only 23 chromosomes).

Detailed explanation-4: -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-5: -In humans, 23 such chromosomes occur in pairs and thus totalling 46 chromosomes. These 23 pairs can be divided into autosomes and allosomes. The first 22 pairs come under autosomes, and the 23rd pair is the allosome or sex chromosome.
