Are spermatids diploid or haploid?

Spermatids

1. These are immature sperm cells that are produced by primary spermatocytes after meiotic division.
2. These spermatids further develop into mature sperms in the testis.
3. Spermatids are haploid cells.
4. They are formed after meiosis in the testis.
5. These haploid cells mature into sperms through spermiogenesis and after fertilization, it becomes diploid zygote.
