For females it occurs in utero,
for men it begins at puberty and continues to death.
23. Every human has 46 chromosomes, so each sex cell contributes 23.
Each parent sex cell gives 23 chromosomes to their offspring in humans
Half the genetic information in a sex cell
in the testes

Oh, dude, like, each sex cell goes through this thing called meiosis, where it divides twice. So, technically, there are two divisions that happen to create each sex cell. It's like the cell's way of saying, "I need some space, man."
If their are 36 chromosomes, the sex cells would have 18 chromosomes each.
Skunks, like many mammals, have a diploid chromosome number of 38. This means that each skunk's sex cells (sperm and eggs) will have half that number, resulting in 19 chromosomes in each sex cell.

A sex cell is, by definition, a male sex cell or a female sex cell. Both are 1N and each contains half the genetic material of the parent that produced the cell. Parental traits are not combined until fertilization has occurred.
Half the number of chromosomes in body cells😜😘
They are body cells. There is only one type of sex cell for each gender: sperm for males and egg cells for females.
