Final answer:
When spermatogonia divide, they produce a spermatogonium and a spermatocyte. Spermatogonia are the least mature cells in the testis and they have the ability to differentiate. The spermatocyte is the next stage in spermatogenesis.
Step-by-step explanation:
When spermatogonia divide, the two daughter cells produced are a spermatogonium and a spermatocyte. Spermatogonia are the least mature cells in the testis and they have the ability to differentiate into various cell types. After division, one daughter cell remains as a spermatogonium to replenish the reserve, while the other becomes a primary spermatocyte, which is the next stage in spermatogenesis.
