Detailed explanation-1: -The zygote undergoes a process known as mitosis, in which it replicates its chromosomes (which carry each parent’s DNA) and then divides, resulting in two identical cells. These cells are called totipotent and have the ability to develop into a new organism.
Detailed explanation-2: -Embryonic differentiation is the process of development during which embryonic cells specialize and diverse tissue structures arise. Animals are made up of many different cell types, each with specific functions in the body.
Detailed explanation-3: -The embryonic stage lasts through the eighth week following fertilization. During this time, the embryo grows in size and becomes more complex. It develops specialized cells and tissues and starts to form most organs.
