Provide a schematic labelled diagram to represent oogenesis.

(N/A) The process of oogenesis involves the following stages:
$1$. Oogonia ($46$ chromosomes) undergo mitosis and differentiation during fetal life to form Primary oocytes ($46$ chromosomes).
$2$. The Primary oocyte completes the $1^{st}$ meiotic division (prior to ovulation) to form a Secondary oocyte ($23$ chromosomes) and a First polar body ($23$ chromosomes).
$3$. The Secondary oocyte undergoes the $2^{nd}$ meiotic division to form an Ovum ($23$ chromosomes) and a Second polar body ($23$ chromosomes).
