At which stage, a small number of primary oocytes are recruited each month?
a) childhood stage
b) at puberty
c) at adulthood
d) at infant stage
Each month how many primary oocyte/s is/are selected each time to continue meiosis after first arrest at prophase-I?
a) only one
b) two
c) three
d) many
Which of the following cell/s is/are produced after the completion of meiosis-I during oogenesis?
a) two secondary oocytes
b) one secondary oocytes
c) one first polar body
d) both b and c
Explanation both secondary oocyte and first polar body are dissimilar in size with haploid number of chromosomes.
In humans, the secondary oocyte arrests in ………stage during oogenesis.
a) prophase-II
b) metaphase-II
c) anaphase-II
d) telophase-II
Explanation: it is this cell that is ovulated during each menstrual cycle
What will happen to arrested secondary oocyte at metaphase-II stage if not penetrated by sperm?
a) it remains in the fallopian duct
b) it remains in uterus
c) it goes back to ovary
d) it simply deteriorates
What
will happen to arrested secondary oocyte at metaphase-II stage if penetrated by
sperm?
a) it remains in the fallopian duct
b) it completes meiosis-II
c) it goes back to ovary
d) it simply deteriorates
Explanation one large ovum and a tiny second polar body are produced with haploid number of chromosomes
