How many chromosomes are present in a typical human body cell?

A typical human body cell contains 46 chromosomes. This is because human cells are diploid, meaning they have two sets of chromosomes—one inherited from each parent. Each set consists of 23 chromosomes, which collectively results in 46 chromosomes. This arrangement is crucial for maintaining the stability of genetic information during cell division, as it ensures that each daughter cell receives an exact copy of the genetic material.

In the context of human biology, the diploid number is important for processes such as growth, development, and tissue repair. During reproduction, however, gametes (sperm and egg cells) are haploid, containing only 23 chromosomes, which allows for the restoration of the diploid number upon fertilization. Understanding the chromosome number is fundamental in studies related to genetics, inheritance, and variations within a species.
