In a certain male individual, primary spermatocytes do not divide into secondary spermatocytes, yet still undergo spermiogenesis and form mature sperm. How will the resulting sperm differ from normal sperm?
A)The abnormal sperm will have 23 chromosomes instead of 46.
B)The abnormal sperm will be diploid instead of haploid.
C)The abnormal sperm won't develop a tail or acrosomal cap.
D)The abnormal sperm are all type A cells.

Normal spermatogenesis involves the division of primary spermatocytes (which are diploid) into secondary spermatocytes (which are haploid) through meiosis I. If this division does not occur, the resulting sperm would retain the diploid number of chromosomes (46) instead of the normal haploid number (23).
