How many pairs of chromosomes does a normal human somatic cell have?
46 chromosomes are there in a human somatic cell. 22 pairs of homologous chromosomes are there with one pair of XX (in case of females) and one pair of XY (in case of males). Hence, 22 pairs of chromosomes + one pair of XX/XY chromosomes gives 23 pairs of chromosomes, i.e., 46 chromosomes. 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. Answers. Relevance. Rating Newest Oldest. Best Answer: A somatic cell is a simple body cell (not a Germ cell-aka gamate) so therefore in a normal human cell, you have 23 PAIRS of chromosomes in each cell-this is 46 chromosomes in total which are maintained through the process of mitosis in each cell cycle. 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. Therefore there is a total of 23 pairs of chromosome in a human body cell. However the human gametes formed by meiosis have haploid number of chromosomes i.e. they have only 23 chromosomes instead of 46; so that after fertilization the zygote has 23 pairs of chromosome(23 from the sperm and 23 from the ovum). There are 46 chromosomes (23 pairs) in a human body cell with the exception of the sex cells. One of each pair is inherited from the mother's egg, the other from the father's sperm. When the sperm and egg unite in fertilization, they create a single cell, or zygote, with 46 chromosomes. Somatic cells (body cells) are haploid cells. They have 23 pairs of chromosomes. Reproductive cells (gametes) have half the normal number i.e. 23. This is because two gametes (one male and one female) have to fuse hence, restoring the original number of 23 pairs. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. A human body cell has 46 chromosomes (23 pairs) with the exception of the sex cells. One of each pair is inherited from the mother's egg, the other from the father's sperm. When the sperm and egg unite in fertilization, they create a single cell, or zygote, with 46 chromosomes.
