Are all autosomal chromosomes the same?
An autosome is any chromosome that is not a sex chromosome. The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosome pairs which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA.

Do all humans have the same autosomes?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females.
Which chromosomes are called autosomes?
The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female. Females have two X chromosomes, while males have one X and one Y chromosome.
What are the 44 autosomes?
Autosomal: Pertaining to a chromosome that is not a sex chromosome. People normally have 22 pairs of autosomes (44 autosomes) in each cell, together with 2 sex chromosomes, X and Y in a male and X and X in a female.
What is the difference between autosomes and homologous chromosomes?
Ask Biology: What’s the difference between autosomes and homologous chromosomes? An autosome is any non-sex-determining chromosome, in humans that refers to the first 22 pairs. A homologous pair of chromosomes are those which are nearly-identical, one being given from each parent.
