The autosomal chromosomes have almost all of your genes on them. There are 22 pairs of them in every cell in your body except sperm and eggs. One chromosome of each pair came from your mom and the other from your dad when their gametes got fertilised and a zygote was formed. Sex chromosomes are only 1 pair.
A sex chromosome , also referred to as an allosome , heterotypical chromosome , or heterochromosome , [1] [2] or idiochromosome [3] is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes, a typical pair of mammal allosomes, determine the sex of an individual created in sexual reproduction. Autosomes differ from allosomes because autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell , whereas members of an allosome pair may differ from one another and thereby determine sex. Nettie Stevens and Edmund Beecher Wilson both independently discovered sex chromosomes in
The chromosomes, apart from the sex chromosomes , are known as autosomes of an organism. The number of chromosomes varies from one organism to others. In humans, there is a total of 46 chromosomes or in pair of
Many animals, including humans have two types of chromosomes: Autosomes and sex chromosomes. Sex chromosomes are those that are needed for determining sex male or female of an individual. Autosomes are all the rest of the chromosomes that are not needed for sex determination. Autosomes are chromosomes that do not carry any genes that determine the sex of the individual. Autosomes are referred to numerically e.
