Question

who shares the exact same dna code?
○ parents with a biological child
○ identical twins
○ siblings
○ no one
○ fraternal twins

Explanation:

Identical twins form from a single fertilized egg that splits into two embryos, so they inherit the exact same DNA code. Other options (parents/child, siblings, fraternal twins) share only partial DNA, and "no one" is incorrect because identical twins do share exact DNA.

Answer:

B. identical twins
