Question
Chapter 46, Problem 2IQ
Summary Introduction
To list: The three mechanisms that may help to ensure that the gamete release is synchronized when fertilization is external.
Introduction: Fertilization is the process of the union of male and female sex cells to form a zygote that grows into an individual. There are two mechanisms of fertilization, namely the external and internal mechanisms. External fertilization refers to the fertilization of eggs that occurs outside the body and mostly in water. Internal fertilization is the fertilization of eggs in the female reproductive tract.

a)
Give a detailed account of the hormonal control of the human menstrual
cycle.
Briefly explain the similarities and differences between oogenesis and
spermatogenesis.
b)

The male reproductive system mass produces large quantities of gametes each day, whereas the female reproductive system produces an average of a single gamete each month. c. The excretory and reproductive systems both use the urethra in males, whereas in females, there are separate tubes for the excretory and reproductive systems. d. The structures that produce gametes are exterior to the body in the male reproductive system, whereas the gametes are produced inside the body for females.arrow_forward
