Chapter 29, Problem 5RQ
Summary Introduction
Introduction:
In mammalian egg zona pellucida is present; when sperm penetrate this membrane a diploid zygote (single cell) will be formed. Zygote cell will undergo for the multiple rounds of the cleavage for the development of gamete. Cleavage termed as the event followed by the rapid and multiple cell division to form the developmental stages. Morula is the dividing cells in the first stage of development of gamete.
