Question
Chapter 30, Problem 7WIO
Summary Introduction
To determine:
Whether the given cell types are haploid or diploid and the way they are related to each other.
Introduction:
The development of sexually reproducing animal starts with the zygote. The first cell starts to divide just after the completion of the fertilization. The cells divide and die in a coordinated way as the embryonic animal grows. This process makes the body’s distinctive form and function in shape.
