Question
How many chromosomes does a human body have? Are these chromosomes distributed in all cells, or do they only exist in a specific cell population?
Answer
The normal human body contains 23 pairs of chromosomes in its somatic cells, totaling 46 chromosomes. These chromosomes have specific shapes and structures and are distributed in all somatic cells. However, in certain cell types, such as germ cells (sperm or egg), the chromosome number can differ. Abnormalities in chromosome number, such as changes in shape or structure or quantity, can lead to chromosomal disorders.
