how many chromosomes do humans have in somatic cells?
30770
Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition. Human gametes have 23 chromosomes, one each of 23 unique chromosomes.

Humans usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication.

​Somatic Cells A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring.

Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition.

Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n). Retroviruses that contain two copies of their RNA genome in each viral particle are also said to be diploid.

Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID. Chromosomes come in pairs, called Homologous Pairs (or homologs).

Humans normally have 46 chromosomes in each cell, divided into 23 pairs.

The number of chromosomes depends entirely on what species you are looking at. Humans have 23 pairs of chromosomes, so our hearts have 46 chromosomes...

remember that a typical cell in your body has 46 chromosomes (23 pairs of homologous chromosomes) suppose that human sperm and eggs were produced by mitosis.

Consequently, all of the somatic cells in human females contain two X chromosomes, and all of the somatic cells in human males contain one X and one Y chromosome (Figure 3). The same is true of all other placental mammals — males produce X and Y gametes, and females produce only X gametes (Figure 4).

The chromosome has a narrow "waist" at a specialized region called the centromere, where sister chromatids are attached. None of the listed responses is correct. Each human somatic cell has a total of 46 chromosomes. Only half are maternal chromosomes.

All body cells expect for the reproductive cells. How many chromosomes do human somatic cells contain? 46 chromosomes composed of two sets of 23 chromosomes (2n; diploid).

Human body cells (somatic cells) have 46 chromosomes. ... The matched pairs of chromosomes in a diploid organism are called homologous chromosomes. Homologous chromosomes are the same length and have specific nucleotide segments called genes in exactly the same location, or locus.

Expert Answer 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.

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).

Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39.

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).
