how many chromosomes does a normal diploid somatic cell have?
67241
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.
81574
Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes.
323621
Germ cells have only half the number of chromosomes as a diploid cell   one of each pair. The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis.
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.

A diploid cell is a cell that contains two complete sets of chromosomes. ... A homologous chromosome pair consists of one chromosome donated from the mother and one from the father. Humans have 23 sets of homologous chromosomes for a total of 46 chromosomes.

Somatic cells and gametes. -Each body cell contains a set of 46 chromosomes, which come in 23 pairs.

Chromosome Numbers 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.

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.

A diploid cell is a cell that contains two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be a homologous chromosome set.

Questions: 1. Dogs have 78 chromosomes in their diploid cells.

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.

Since each chromosome consists of one DNA molecule, each human somatic cell contains 46 chromosomes. A DNA molecule with part or all of the genetic material of an organism. Each of the two threadlike strands into which a chromosome divides longitudinally during cell division.

Germ cells have only half the number of chromosomes as a diploid cell   one of each pair. 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).

The typical human body cell contains 46 chromosomes.

For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes. In humans, this is 23 unpaired chromosomes.

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).

​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.
