Multiple Choice
In human meiosis, the mature female egg cell is the:
A
Secondary oocyte (haploid cell arrested in metaphase II before fertilization)
B
Primary oocyte (diploid cell arrested in prophase I)
C
Polar body (small haploid cell that typically degenerates)
D
Ovum (haploid gamete produced after completion of meiosis II)
Verified step by step guidance1
Understand the stages of oogenesis in human females, which is the process of egg cell development through meiosis.
Identify that the primary oocyte is a diploid cell arrested in prophase I of meiosis and has not yet completed the first meiotic division.
Recognize that the secondary oocyte is a haploid cell arrested in metaphase II, which is the stage at which it is typically ovulated and awaits fertilization.
Know that the polar body is a small haploid cell produced during meiosis that usually degenerates and does not develop into a mature egg.
Conclude that the mature female egg cell, or ovum, is the haploid gamete produced only after the secondary oocyte completes meiosis II following fertilization.
