Difference Between Autosome and Allosome
Difference Between Autosome and Allosome are as given below:
| Feature | Autosomes | Allosomes (Sex Chromosomes) |
|---|---|---|
| Location | Found in both males and females | Found in pairs in females; XY in males |
| Number | Typically present as pairs (homologous) | One pair of sex chromosomes (XX or XY) |
| Inheritance | Inherited from both parents | Inherited from both parents |
| Role in Sex Determination | Not involved in sex determination | Directly involved in sex determination |
| Genetic Diversity | Contribute to overall genetic diversity | Contribute to genetic diversity and sex determination |
| Determination of Sex-Linked Traits | Not directly involved in sex-linked traits | Directly involved in sex-linked traits |
| Hemizygosity (in XY system) | Not applicable | Males are hemizygous for X-linked genes |
| Expression in Males (in XY system) | Not applicable | Only one X chromosome is active in males |
| Example in Humans | Chromosomes 1-22 | X and Y chromosomes |
What are Autosomes and Allosomes? – Difference and Functions
Autosomes and Allosomes are two types of chromosomes found in the cells of living organisms, particularly in sexually reproducing species. Autosomes chromosomes are somatic chromosomes that determine an organism’s physical characteristics and allosome chromosomes are sex chromosomes that determine an organism’s sex and sex-linked inheritance. In this article, we will discuss the Autosomes and Allosomes chromosomes – characteristics, their functions, and the differences between Autosomes and Allosomes.
