Solution

The correct option is D

50, 50, 100


Identical twins have the same genetic makeup. However, they may not look exactly identical to one another. Identical twins thus, share 100% of their DNA. Siblings and fraternal twins on an average, share 50% of their genes, i.e., close to half of their genetic makeup is similar to that of each other.
