how many sets of chromosomes are there?
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.

The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. Because they have only half the total chromosomes in a somatic cell, they are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.

Humans have 46 chromosomes, That number of chromosomes will be found a, in cells in anaphase. - : b. in egg and sperm cells. in somatic cells.

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.

Humans are born with 46 chromosomes in 23 pairs. The X and Y chromosomes determine a person's sex. Most women are 46XX and most men are 46XY.

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.

Each person has 23 pairs of chromosomes, or 46 in all. For each pair, you get one chromosome from your mother and one chromosome from your father. About 1 in 150 babies is born with a chromosomal condition.

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.

How many chromosomes do people have? 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.

Originally Answered: How many sets of chromosomes are present in human zygote? Human cells have 23 pairs of chromosomes (22 pairs of autosome + 1 pair of sex chromosome),making a total of 46 chromosomes per cell.

Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. The letter n is used to represent a single set of chromosomes; therefore a diploid organism is designated 2n.

refers to the total number of chromosomes that a diploid cell contains. Cells, in human and animal context, typically have either one or two sets of chromosomes, which store DNA. A single set of human chromosomes contains 23 chromosomes, so there are "2n", or 46, total cells in a haploid human cell.

We have 23 sets of chromosomes, 2 chromosomes per set = 46 chromosomes in each cell. But each chromosome has 2 DNA strands (that form the double helix), so 46 x 2 = 92 DNA strands/cell.

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).
