Humans have 23 pairs of chromosomes, for a total of 46 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.

Information. 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.

Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes.

Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes. This is the n, or haploid, state.

Thus, each human cell contains a total of 46 chromosomes—22 pairs common to both males and females, plus two so-called sex chromosomes (X and Y in males, two Xs in females).

Most people have 46 chromosomes in each of their cells. People with Down syndrome have 47, and because of that they may look and learn differently.
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.

Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception.

Answer and Explanation: The cells of a human each contain 23 pairs of chromosomes, for a total of 46 chromosomes in all. It doesn't matter if it is a skin cell, a liver...

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.
107006
Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
430477
In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes.
76074
At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis).
101945
After meiosis, half the number as were in the starting parent cell. Humans have 46 chromosomes, and the starting parent cell - whether we are talking about mitosis or meiosis - has 46 chromosomes. After mitosis, each of the 2 daughter cells will also have 46 chromosomes.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

Along the segments of our DNA, genes are neatly packaged within structures called chromosomes. Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception.
