how many chromosomes pairs do humans have in a cell?
3941
Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
1033054
A human's 46 chromosomes can be grouped into 23 pairs of chromosomes called... homologous chromosomes. similar in shape and size, and that the two chromosomes carry the same gene.
323032
Each species has a characteristic set of chromosomes with respect to number and organization. For example, humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes called autosomes, 1 through 22, and one pair of sex chromosomes, X and Y.
1253394
Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs.
938629
The human genome is the genome of Homo sapiens. It is made up of 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 24 distinct human chromosomes: 22 autosomal chromosomes, plus the sex-determining X and Y chromosomes. Chromosomes 1-22 are numbered roughly in order of decreasing size.
106145
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females.
492923
Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
1047444
Almost every cell in our body contains 23 pairs of chromosomes, for a total of 46 chromosomes. Half of the chromosomes come from our mother, and the other half come from our father. The first 22 pairs are called autosomes.
197168
DNA is organized into structures called chromosomes. As shown in the animation, most humans have a total of 46 chromosomes in each cell: 22 pairs of matching chromosomes (autosomes) and one pair of sex chromosomes (allosomes).
500269
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
1204419
Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).
335951
Cells of human being have 23 pairs of chromosomes, 22 pairs of autosomes and one pair of sex chromosome. Hence, each individual has 46 chromosomes in their cells. Hence, the number of chromosomes present in a nerve cell of a human being are 46 chromosomes.

Diploid cells do not have a set number of chromosomes that depends on the species. Diploid means that the chromosomes in the cell are in pairs ie two of each type. A human diploid cell has 46 chromosomes in 23 pairs.
641341
As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. The cell has two sets of each chromosome; one of the pair is derived from the mother and the other from the father.
799496
In human somatic cells, there are 23 pair (2n) of chromosomes, and there are 23 pairs in all cells except in gametes. Of the 23 pair in somatic cell, 22 pair are autosomes, while two are sex chromosomes.

In a human karyotype, the 46 chromosomes of the human genome are arranged into 23 pairs. Encyclopædia Britannica, Inc. An organism with any multiple of the diploid number of chromosomes is said to be polyploid.
1034091
Chromosomes come in matching pairs, one pair from each parent. Humans, for example, have a total of 46 chromosomes, 23 from the mother and another 23 from the father. With two sets of chromosomes, children inherit two copies of each gene, one from each parent.
