is this statement true that 512 spermatids are formed from single spermatogonium and how is this possible???

Dear Student, Yes, this statement is true as spermatogonium divides and mature. The newly formed descendants remain tied together through cytoplasmic bridges which results in synchrony of the differentiation of each clone of the germ cell. Thus forming 512 spermatids from single spermatogonium. Thank You!
