How many autosomes and sex chromosomes does each human somatic cells have? Best Answer: humans have 22 pairs of autosomes (44 chromosomes) and 1 pair of sex chromosomes ( 2 chromosomes). It all adds up to 23 pairs of chromosomes (46 chromosomes). Human somatic cells contain 22 pairs of autosomes and either two X chromosomes (in females) or an X and a Y chromosome (in males).

- 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.

Chromosome Most species have, on average, 10 to 50 chromosomes. With 46 chromosomes, humans fall well within this average. The 46 human chromosomes are arranged in 23 pairs. One pair of the 23 constitute the sex hormones, called the X and Y chromosomes. Males have both an X and a Y chromosome, while females have two X chromosomes.

How many chromosomes are in each human sex cell? A regular human sex cell (unless something goes wrong) is haploid (meaning that it has half the chromosomes of a normal body cell). Since normal human body cells have a total of 46 chromosomes (23 pairs), a human sex cell (like sperm) has 23 chromosomes.As there are 23 chromosomes, the sex cells do not have pairs of chromosomes. The fact that sex cells only have half the number of chromosomes as regular cells (no pairs) is a very good thing. regular human sex cell (unless something goes wrong) is haploid (meaning that it has half the chromosomes of a normal body cell). Since normal human body cells have a total of 46 chromosomes (23 pairs), a human sex cell (like sperm) has 23 chromosomes.

How many chromosomes do humans have in each cell? Humans have 46 chromosomes in each cell. During fertilization of the egg, the sperm nucleus containing 23 chromosomes from the paternal side fuses with the nucleus of the egg that contains 23 chromosomes from the maternal side. The result is the zygote that contains 46 chromosomes (23 pairs of chromosomes; one of each pair from either parent). From that single celled zygote comes all the cells of your body today that is formed as a result of uncountable number of cell divisions.
