Autosomes vs Chromosomes
Autosomes and chromosomes are closely related but refer to different aspects of the structures found within the cell nucleus that carry genetic information. Here are the differences between the two:
Feature |
Chromosomes |
Autosomes |
Definition |
Chromosomes are structures within cells that contain DNA and proteins. They carry genetic information. |
Autosomes are chromosomes that determine traits not directly related to the sex of an organism. |
Types |
Includes all the chromosomes in a cell, both autosomes and sex chromosomes (X and Y in humans). |
Refers specifically to non-sex chromosomes. In humans, these are from chromosomes 1 till chromosme 22. |
Function |
Chromosomes are responsible for storing and transmitting genetic information. They affect all traits and biological functions. |
Autosomes carry the majority of an individual’s genetic material influencing physical traits and functions excluding sex determination. |
Number |
The number of chromosomes varies by species. Humans have 46 chromosomes in total. |
Humans have 44 autosomes (22 pairs), which is a subset of the total number of chromosomes. |
Role in Sex Determination |
Sex chromosomes (a subset of chromosomes) play a direct role in determining the sex of an individual. |
Autosomes do not play a direct role in determining the sex of an individual. |
Autosomes
Autosome chromosomes are non-sex chromosomes. This means they are not involved in determining an individual’s sex. Instead, they carry genetic information about various traits and characteristics. There are 22 pairs of autosomes in the human body.
Understanding the autosome function and example helps in learning the role of autosomes in determining traits and genetic disorders in humans and other organisms. This article will cover autosome vs sex chromosome, autosome function, and more in detail.
