How many spermatozoa and ova will be formed by 50 primary spermatocytes and 50 primary oocytes, respectively?

Step-by-step solution

During spermatogenesis, one primary spermatocyte undergoes meiosis to produce four haploid spermatozoa. Number of spermatozoa produced by 50 primary spermatocytes = 50 4 = 200 . During oogenesis, one primary oocyte undergoes meiosis to produce only one functional ovum and polar bodies. Number of ova produced by 50 primary oocytes = 50 1 = 50 . Thus, 200 spermatozoa and 50 ova will be formed. Answer: 200 and 50
