Question

All of these children (including the fraternal twin sisters in the front row)

are the biological children of the two parents in the middle of the picture.
Based on everything that you have learned in this unit, explain why these
brothers and sisters do not look exactly alike. Include the processes of cell
division and the rules of genetics in your answer.

Answer 1

Step-by-step explanation:

Because in the fetus stages of fraternal twins two different eggs get fertilized. Therefore, genetics won't be the same for both twins. But if they were identical twins the fertilized egg was to divide and the two zygotes would've carried the same genetics of each other.
