If the expression level of each pair of autosomes (gray for both males and females) is set to 1.0, then the expression level of the two X chromosomes in females (pink) and the single X chromosome in males (blue) is also equal to 1.0.
Chromosomes that do not differ between sexes.
A measure of the expected homozygosity where alleles are identical by descent.
autosomes the 22 pairs of human chromosomes that are not sex chromosomes.
autotrophic certain bacteria that synthesize their own foods.
axon the long extension of a neuron.
Autosomes all the chromosomes other than the X and Y chromosomes
(auto = self; soma = body)
Autotroph an organism‚ such as a plant‚ which makes its own food
(auto = self; troph = food‚ nourish‚ nourishment) ...
autosomes The chromosomes other than the sex chromosomes. Each member of an autosome pair (in diploid organisms) is of similar length and in the genes it carries.
22 pairs of autosomes
1 pair of X chromosomes
The karyotype of the human male contains:
the same 22 pairs of autosomes
one X chromosome
one Y chromosome ...
(y) How many autosomes are found in the human haploid?
(z) What kind of nuclear division occurs during cellular reproduction that involves no change in ploidy?
Humans have 23 pairs of chromosomes, 46 in all: 44 autosomes and two sex chromosomes. Each parent contributes one chromosome to each pair, so children get half of their chromosomes from their mothers and half from their fathers.
Humans have 23 pairs of chromosomes (46 total) chromosomes. Two of these are called sex chromosomes, the other 44 are called autosomes.
The human genome has 44 autosomes (22 pairs) (figure 1).
Autosomal — A gene is autosomal if it is located on an autosome. A gene's inheritance pattern is also referred to as autosomal if the pattern corresponds to that of known autosomal genes.
Genome -- all of the genes carried by a single gamete; the DNA content of an individual, which includes all 44 autosomes, 2 sex chromosomes, and the mitochondrial DNA. Genotype -- genetic constitution of an organism.
Of these, 22 are autosomes and 1 is a sex chromosome.
Clones A group of cells derived from a single ancestor.
Cloning The process of asexually producing a group of cells (clones), all genetically identical, from a single ancestor.
Most genes are carried on autosomes, the twenty-two pairs of chromosomes that do not determine sex. Males and females are equally likely to inherit disease genes on autosomes and develop the related diseases, called autosomal disorders.
In 1959 Susumu Ohno showed that the two X-chromosomes of mammals were different: one appeared like the autosomes; the other was condensed and heterochromatic (Ohno S, Kaplan WD, ...
We actually have a total of 23 pairs of chromosomes in these cells, for a total of 46 chromosomes, but two of those are referred to by letter rather than by number and are called sex chromosomes rather than autosomes, ...
Unlike the twenty-two pairs of autosomes, there is no recombination between the X and most of the Y chromosome.
Mothers give 22 autosomes (1-22) and an X chromosome. Fathers give us 22 autosomes and either and X or a Y chromosome. The father determines the sex of his offspring. If the sperm contains an X chromosome, the baby will be a girl.
The diploid human genome consists of 46 chromosomes, 22 pairs of autosomes, and one pair of sex chromosomes (the X and Y chromosomes).
Now that's a significant difference from the standard way of doing genetics which is talking about the autosome or chromosomes because unlike the autosomes, the other non-sex chromosomes, males only get one of those x chromosomes.
Diploid set for humans; 2n = 46
Autosomes; homologous chromosomes, one from each parent (humans = 22 sets of 2)
Sex chromosomes (humans have 1 set of 2)

10.2.2 Distinguish between autosomes and sex chromosomes.
Sex chromosomes are the ones that determine your gender. These are X and Y (XX in females, XY in males).

A human cell contains 23 pairs of homologous chromosomes: 22 of them are homologous non-sex chromosomes (or autosomes) and 1 homologous pair of sex chromosomes. In females, the homologous sex chromosomes are 2 X's; in males the X and Y chromosomes.
A chromosome not involved in sex determination. The diploid human genome consists of a total of 46 chromosomes: 22 pairs of autosomes, and 1 pair of sex chromosomes (the X and Y chromosomes).
