What number and types of chromosomes are found in a somatic cell in an animal?

Each species of eukaryote has a characteristic number of chromosomes in the nuclei of its cells. Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid.

What number and types of chromosomes are found in a somatic cell in an animal with a diploid number of 48 quizlet?

For an animal with a diploid number of 48 (2n = 48), the number of chromosomes in the somatic cells is 48 and the number of chromosomes in each haploid set is 24 (n = 24).

What number and types of chromosomes are found in a somatic?

1. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, one each of 23 unique chromosomes, one of which is a sex chromosome.

Do somatic cells have 23 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.

What is meant by an allele?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

What is the main difference between Chromatin and chromosomes?

Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.

How many genes are in a chromosome?

Chromosome 1 likely contains 2,000 to 2,100 genes that provide instructions for making proteins.

What are the types of somatic cells in your body?

Somatic cells are all cells of the body apart from gamete (sperm cells and egg cells). As such, they include cells that make up different parts of the body including liver cells, skin cells, and bone cells among others. Mature somatic cells are highly specialized and therefore perform very specific functions.
