Ответ:
I tell my students that it's like having three trays of cookies, each tray having a different kind of cookie. Your instructions are that you may have any two cookies that you want. Can you have two from the same tray? Yes. Can you have two different kinds? Yes, you can have one of one kind and one of a second kind. Can you have one from each of the three trays? No, you can only have two cookies.
That's how multiple alleles work. Blood type is controlled by multiple alleles: A, B, and O. Can a person have AA? Yes. Can a person have OO? Yes. Can a person have AB? Yes. Can a person have BO? Yes (but it makes everybody laugh). Can a person have ABO? No, only two alleles and no more.
So the answer is No, a person does not have more than two alleles for a single gene.
Of course there are exceptions, but not normal exceptions. Only abnormal exceptions that happen when a person has an unusual number of chromosomes. If you are just learning genetics, you don't have to worry about these exceptions yet.

The answer is differentiation, or the second option.
Explanation:
Differentiation is a developmental process by which unspecialized cells change into specialized cells with distinctive structural and functional characteristics. Through differentiation, cells develop into tissues and organs.
hope this helped :)
