How many chromosomes do humans have? The typical number of chromosomes in a human cell is 46: 23 pairs, holding an estimated total of 20,000 to 25,000 genes. One set of 23 chromosomes is inherited from the biological mother (from the egg), and the other set is inherited from the biological father (from the sperm).
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).
