how many pairs of chromosomes does a genetically-normal human being have?
45175
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. The 23rd pair, the sex chromosomes, differ between males and females.

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.
639033
Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
649790
Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y.
1460513
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).
980424
Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA tied by hydrogen-bonds to each other making the classic DNA double helix (double-stranded DNA). So, in total there are 46*2=92 strands of DNA in each diploid human cell!
1181489
Every human cell has 23 pairs of chromosomes for a total of 46 (aside from sperm and egg cells, which each contain only 23 chromosomes).
778581
Of the 23 pairs of chromosomes in a human, how many of them are sex chromosomes?
1041200
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.
494619
Humans are diploid organisms, carrying two complete sets of chromosomes in their somatic cells: one set of 23 chromosomes from their father and one set of 23 chromosomes from their mother. The two sets combined provide a full complement of 46 chromosomes.
1175322
The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells. There are 22 pairs of autosomal chromosomes and one pair of sex chromosomes.
652456
While great apes all have 48 chromosomes (24 pairs), humans have only 46 (23 pairs).
1412823
In humans. Humans have a total of 46 chromosomes, but there are only 22 pairs of homologous autosomal chromosomes. ... The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father.
