sperm cell
The cell type that has 22 autosomes and an X sex chromosome is a gamete, such as an egg or sperm cell.
Haploid
A macrophage is a type of white blood cell; it is not a chromosome.
Prokaryotic Cell
Chromosomes are typically located within the nucleus of a cell. Each type of chromosome has its specific location within the nucleus, but their organization can vary depending on the stage of the cell cycle and the cell type. Within the nucleus, chromosomes are organized into distinct territories.
The cell type that has 22 autosomes and an X sex chromosome is a gamete, such as an egg or sperm cell.
A somatic cell with two of each type of chromosome has a diploid chromosome number. This means that the cell has a complete set of chromosomes, one from each parent.
Chromosome
A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
The process that produces autosomes is meiosis. Meiosis is the type of cell division that results in the formation of gametes (sperm and egg cells) and involves two rounds of division, resulting in four daughter cells with half the number of chromosomes as the parent cell. Autosomes are chromosomes that are not involved in determining an individual's sex.
A diploid cell with an extra chromosome. Basically a diploid with an extra chromosome of one type, producing a chromosome number of the form 2n + l.
A macrophage is a type of white blood cell; it is not a chromosome.
Haploid

Prokaryotic Cell
An autosome is a non-sex chromosome. It is an ordinarily paired type 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.
