Draw a schematic diagram showing spermatogenesis vis-à-vis oogenesis. Label the stage of development and chromosome number of daughter cells at the following levels of maturation:  (a) mitotic proliferation (b) meiosis I and II (c) maturation.

In January 2009, Natalie Suleman successfully gave birth to octuplets and became known as Octomom. She already had 6 children, and all 14 of her children were conceived via in vitro fertilization (IVF). IVF involves removing eggs from the ovary, fertilizing them with sperm in a petri dish, and transferring the resulting embryos back into a uterus to develop. It is common for two or three embryos to be transferred into the uterus of a woman undergoing IVF to increase the chances of at least one of them surviving. When Ms. Suleman became pregnant with her octuplets, Dr. Kamrava had transferred 12 embryos. His license was revoked in 2011.Multiple eggs are required for IVF to produce functional embryos because some eggs are not fertilized or do not develop normally after fertilization. Which of the following hormones would be used to stimulate the ovaries to produce multiple eggs? Select one: a. Testosterone b. FSH c. Progesterone d. Estrogen

ARRANGE THE FOLLOWING EVENTS IN CORRECT SEQUENCE from 1-13: Penetration of the zona pellucida Cortical reaction 1st cleavage Acrosomal membranes rupture, and release their enzyme contents Penetration of the corona radiata Depolarization of egg membranes Migration of cortical cytoplasm to form gray crescent Sperm attach loosely on the zona pellucida Zona reaction Oocyte completes meiotic division    ZP3 tenaciously binds acrosome-intact sperm Release of Ca+2 in egg cytoplasm from its bound state Amphimixis
