Does each cell have 46 chromosomes?
Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
What is the chromosome for a female?
Consequently, all of the somatic cells in human females contain two X chromosomes, and all of the somatic cells in human males contain one X and one Y chromosome (Figure 3). The same is true of all other placental mammals — males produce X and Y gametes, and females produce only X gametes (Figure 4).
How many genders are there?
Most cultures use a gender binary, having two genders (boys/men and girls/women); those who exist outside these groups may fall under the umbrella term non-binary.
