Question

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

• A. 200 and 50
• B. 50 and 200
• C. 100 and 400
• D. 200 and 100

Hint:

One primary spermatocyte gives four sperms, while one primary oocyte gives only one ovum.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
Meiosis of a primary spermatocyte gives four spermatids, each becoming a sperm. Meiosis of a primary oocyte gives one ovum and polar bodies.

Step 2: Calculation
Sperms: \(50 \times 4 = 200\).
Ova: \(50 \times 1 = 50\).

Step 3: Conclusion
200 spermatozoa and 50 ova are formed.

Final Answer:
200 spermatozoa and 50 ova are formed. \[ \boxed{\text{(A) }\text{200 and 50}} \]
