I think the correct answer would be they have specific genes activated. Cell differentiation is a process on how cells become specialized. This happens via gene expression. Hope this answers the question. Have a nice day.
Fertilized eggs divide and their cells differentiate because they have specific genes activated.
What is gene regulation?
It is a process whereby specific genes are turned on or off in order to elicit specific traits of functions.
