How many autosomes are in human cells?
Humans have 22 pairs of autosomes. Autosomes are 1 of the 2 types of chromosomes in the human cell and humans get 1 set of 22 from one parent and 1 set of 22 from the other parent.
44 - - - In humans, there are 23 chromosomes in one set. Of these, one is a sex chromosome, and the other 22 are autosomes. So there are 22 autosomes in a human gamete (spermatozoon or ovum). In the zygote and all the body cells subsequently formed from the zygote, there are two sets (the diploid condition) and therefore 44 autosomes (two genetically different versions of each of the 22).
A single human cell contains 23 pairs of chromosomes (22 autosomes and a pair of sex chromosomes ). These are found in all human cells (RBC's and platelets being exception ). So with human body made up of unbountable number of cells, the actual number of chromosomes in the human body is unbountable times 46= unbountable.
Human somatic (body) cells contain two sets of 23 chromosomes. Human gametes (sperm and egg cells) contain one set of 23 chromomes -- 22 autosomes and 1 sex chromosome. Only a sperm cell can carry a y chromosome. A sperm cell can also carry an x chromosome. The ovum can carry only an x chromosome, never a y chromosome. So a cell containing 22 autosomes and a y chromosome must be a sperm cell.
Body cells have "pairs" of chromosomes while sex cells have only single sets of chromosomes. The human body cells have 22 pairs of autosomes and 1 pair of sex chromosomes for a total of 23 pairs or 46 chromosomes. Sex cells for humans will have half of that (because they are not paired) so a total of 23 chromosomes.
What is the normal number and type of chromosomes present in the human body cells of a particular sex?
Human cells have 23 distinct types of chromosomes, including the 22 autosomes and the X or Y sex chromosome. (The autosomes are usually paired and are the same in both sexes.) You inherit one of each type from each of your parents so that the typical human somatic cell has 46 chromosomes. (Sperm and egg cells, of course, have 23 each.) While there is no difference in the 44 autosomnal chromosomes by sex, the sex…
Humans have 22 pairs of homologous non-sex chromosomes (called autosomes), and one pair of sex chromosomes, making a total of 46 chromosomes in a genetically normal human. Each member of a pair is inherited from one of the two parents. In addition to the 22 pairs of homologous autosomes, female humans have a homologous pair of sex chromosomes (two Xs), while males have an X and a Y chromosome.
This depends on the number of chromosomes the species has, and whether or not they have sex chromosomes. Autosomes are non-sex chromosomes, and somatic cells are cells with the full complement of chromosomes, i.e, are not gametes. Let's consider humans as our example. A human somatic cell carries a total of 46 chromosomes (23 homologous pairs). One pair of these are the sex chromosomes (an XX pair for females and an XY pair for males)…
