In body cells we have 2n (diploid) number of chromosomes, which for us would be 46. However, since our gametes are from only the father or mother, then the gametes (sex cells) are 23 chromosomes or haploid (n).
The cells become 2n (haploid) when the two gametes (sex cells from mother and father) join together.
Good luck!

There are 23 chromosomes from the sperm and egg's necleus which joins up to make 46 during fertilisation.

in all body cells, there are 46 of them, 23 from your mom, and 23 from your dad. in the sex cells, there is only 23.

46 and 23, respectively.
The father's sperm and mother's ova each contribute a set of 23 chromosomes; the resulting zygote has 46 chromosomes (as do the subsequent cells).

that all depends on the creature you're talking about.
for a human 46 in somatic and 23 in gamete.
