Which of the following statements is correct regarding the human x chromosomes?

It is present in every somatic cell of male and female.

Further Explanation:

The chromosomes are present in the nucleus of the cell. It consists of DNA material bounded to the protein molecule which is positively charged.

Twenty three pairs of chromosomes are present in every somatic cell of the human. Twenty two pair of chromosomes are referred to as autosomes while one pair of chromosomes is known as sex chromosome. The somatic cells are diploid in nature. Another type of cells are also present in the human body, they are known as gametic cell. These cells are haploid in nature as they have only twenty two chromosome and one sex chromosome.

In the human the sex chromosome denoted by “Y” is known to be responsible for determining the biological sex of the human. If XY chromosomes is present in the cell, it means it is the cells of male but if it is XX chromosome then this means they are male cell.

The karyotype of the human cell is develop by arranging the chromosomes in the decreasing order of their cell.
