What are two major differences between spermatogenesis and oogenesis?
What will be an ideal response?
1 . Four spermatozoa are produced from each precursor cell in spermatogenesis, but only one ovum is formed from each precursor cell in oogenesis.
2 . Spermatogenesis occurs continually and is carried through to completion in about 2 months, meaning that there is always "fresh" sperm. In contrast, the oocytes are all formed before birth and remain in a prolonged prophase of the first meiotic division from fetal life until they are ovulated.
