Select the correct option regarding the given diagram. Assertion(A): Primary spermatocytes undergo meiosis I to form secondary spermatocytes. Reason (R): Secondary spermatocytes undergo mitosis to form spermatids.
Options
- ABoth Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
- CAssertion (A) is true, but Reason (R) is false.
- DAssertion (A) is false, but Reason (R) is true.
Correct answer
C. Assertion (A) is true, but Reason (R) is false.
Step-by-step solution
A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each. The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids.
