Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes.
So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
I think it's that first of all, sex cells undergo meiosis 1 and 2. None of the others do.

A female human has two X sex chromosomes in her cells. A male human has one X and one Y sex chromosome in his cells.
Sex cells have half the number of chromosomes as the original cell, and are said to be haploid. In human sex cells there are 23 chromosomes.
All cells except sex cells are diploid. And sex cells are haploid.
Cause body cells have twice the chromosomes a sex cell has Body cells have 46 chromosomes and sex cells have 23 chromosomes.
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
XX
same as human
23 chromosomes
It becomes a baby. They go through something called mitosis where the cell gets copied in to two. Then it continues the process and basically make a organ and different organs make up baby !
The sex cells have half the chromosomes that were in the parent cell.
