what is an autosomal?

Question

I NEED THE ANSWER FOR A BIG TEST I HAVE

Answer 1

An autosomal chromosome is one that is not used to determine sex. In other words, it is not X or Y. Those two are called sex chromosomes.

Answer 2

An autosome is a non-sex chromosome. It is an ordinary paired, of chromosome that is the same in both sexes of a species. For example, in humans, there are 22 pairs of autosomes. The X and Y chromosomes are not autosomal.

Non-autosomal chromosomes are usually referred to as sex chromosomes, allosomes or heterosomes. An autosomal dominant gene is one on an autosome that is always expressed, even if a single copy exists. The chance is 1 in 2 (50%) for passing this autosomal dominant gene to a particular offspring. There are 23 pairs of chromosomes in humans (44 autosomes, 2 sex chromosome)

Go to this site you will get information on autosomal

Answer 3

An autosomal dominant gene is one that occurs on an autosomal (non-sex determining) chromosome. As it is dominant, the phenotype it gives will be expressed even if the gene is heterozygous. This contrasts with recessive genes, which need to be homozygous to be expressed.

Answer 4

I think this is a term ued for chromosome - autosomal chromosomes are those that you find in every cell, the other types are called gonosomes - the sex chromosomes
