Read the following table comparing spermatogenesis and oogenesis, and identify the row that represents an incorrect comparison. Row Parameter Spermatogenesis Oogenesis (A) Initiation of multiplication phase At puberty During embryonic development (B) Cytoplasmic division in Meiosis I Equal Unequal (C) Stage of gamete released from gonad Mature spermatozoon Mature ovum (D) Post-meiotic morphological differentiation Pr
Options
- ARow (B)
- BRow (C)
- CRow (D)
- DRow (A)
Correct answer
B. Row (C)
Step-by-step solution
In human females, ovulation (release of the gamete from the ovary) occurs at the secondary oocyte stage, not as a mature ovum. The secondary oocyte is arrested at metaphase II of meiosis II, which is only completed later if fertilization occurs. In contrast, in males, mature spermatozoa are released from the seminiferous tubules during spermiation. Therefore, the comparison in Row (C) is incorrect. Row (A) is correct as spermatogenesis begins at puberty while oogenesis begins during embryonic development. Row (B) i
