The basic difference between spermatogenesis and oogenesis is that ________.
A) during spermatogenesis, two more polar bodies are formed
B) in oogenesis, one mature ovum is produced, and in spermatogenesis, four mature sperm are produced from one parent cell
C) the mature ovum is n, while the mature sperm are 2n
D) oogenesis only involves meiosis

Question

Quizplus · Accepted Answer

During spermatogenesis, one parent cell produces four mature sperm, while in oogenesis, one parent cell produces one mature ovum. Additionally, spermatogenesis produces equal haploid gametes (sperm), while oogenesis produces one large haploid gamete (ovum) and several smaller polar bodies. The mature ovum is also 1n, while the mature sperm are 1n. Therefore, option B is the correct answer. Option A is incorrect because during spermatogenesis only four sperm are produced, not two or more polar bodies. Option C is incorrect because the mature ovum is actually 1n, not 2n. Option D is incorrect because both processes involve meiosis.
