Spermatocyte II each having 23 chromosomes and each chromosome is made up of two chromatids. Each Spermatocyte II will then divide by Meiosis II (equational meiosis) to give rise to two Spermatids. Each spermatid will have 23 chromosomes but the number of chromatids per chromosome is ONE.
Since the Spermatid only changes in shape and does not divide to produce a Sperm, the number of chromosomes and chromatids will stay the same as in the spermatid. The sperm will have 23 chromosomes (one chromatid per each chromosome).
Just like spermatogenesis,
