How many chromosomes does a haploid human germ cell have?
Haploid means half of the normal.
A normal human cell has 46 chromosomes or 23 pairs of chromosomes.
So a sex or germ cell has 23 chromosomes none of them paired.
This is so in fertilization the germ cell of the male can combine with the germ cell of a female to form a new normal cell with 46 chromosomes equally paired.
The combination of two haploid cell results in the formation of a new living cell.
