Upon completion of meiosis I and meiosis II in oogenesis, the primary oocyte has developed into:

One first polar body and three second polar bodies

One ovum and three polar bodies

One secondary oocyte and one first polar body

One ootid and three second polar bodies

One secondary oocyte, one ootid, and one ovum

Correct Answer

One ovum and three polar bodies

Explanation

By the end of both meiotic divisions, oogenesis yields one functional ovum (egg) and three polar bodies, all of which eventually disintegrate. The unequal cytoplasmic divisions concentrate nearly all the resources into the single ovum.
