Human Chromosome Types
In humans, each cell typically contains 23 pairs of chromosomes. Thus, a total of 46 chromosomes are found in humans. One chromosome in each pair is inherited from the mother and the other from the father.
The 22 pairs of chromosomes are called autosomes, and the 23rd pair is called the sex or allosome chromosome. There are two types of allosomes: X and Y chromosomes. Allosomes determine an individual’s sex. A person with two X chromosomes is a female (XX), and a person with one X and Y chromosome is a male (XY).
23 Chromosomes – Functions and Types of Chromosomes
Chromosomes are made of DNA molecules and are found in the nucleus of a cell. There are 23 chromosome pairs in humans. Transporting genetic information from one cell generation to the next is the main function of chromosomes. Several genes on each chromosome code for different proteins. The features of the entire organism are influenced by or determined by these genes.
