- Asker's rating. 1  Well there are half the number of chromosomes in sex cells than in normal cells of the body. In a human there are 46 chromosomes in a normal cell. 2  A sex cell has 23, half of the normal 44 regular chromosomes plus a sex chromosome, and a skin cell has 46, the 44 chromosomes and one sex chromosome from each parent.

- Answers. Relevance. Rating Newest Oldest. Best Answer: There are 23 pairs of chromosomes in humans (= 46 total chromosomes) We have 1 pair of sex chromosomes (X & Y, XX for females, & XY for males). The remaining chromosomes are known as autosomes (auto = body), which are chromosomes encoding genes for everything else in our body.

What are Genes & Chromosomes? A normal human cell should contain exactly 46 chromosomes. They are matched into 23 pairs. Pairs one through 22 are numbered by size and appearance, and are the same in males and females. The 23rd pair is referred to as the sex chromosomes. Typically, females have 2 X chromosomes, while males have an X and a Y.

How many chromosomes are in a human cell? Body cells have pairs of chromosomes while sex cells have only single sets of chromosomes. The human body cells have 22 pairs of autosomes and 1 pair of sex chromosomes for a total of 23 pairs or 46 chromosomes. But sex cells (sperm or ovum, known as gametes or diploid cells) contain only 23 chromosomes (unpaired), when they meet (forming a Zygote), the 23 from each male and female gamete form a cell containing 46 chromosomes to make a Haploid cell. Normal body cells (known as a haploid cells) contain 46 chromosomes (or 23 pairs of chromosomes).
