Answer 1

Yes. If the child multiracial/biracial it possible two be fraternal twins and have two very different skin tones. Hope this helped!

Answer 2

They are formed from different eggs and sperms.

Step-by-step explanation:

Fraternal twins appear different a lot of times because they are formed from different eggs and sperms.

Two eggs that are different in their genetic make ups get fertilized by two different sperms which are also different genetically. Hence, two zygotes with different genotypic and phenotypic characteristics results.

This is as opposed to twins that look alike which are formed from the same egg and sperm. A single egg gets fertilized and then divides into two mitotically to give rise to two eggs with the same genetic make up and physical characteristics.
