Question

Two identical twins will not have same:

• A. Fingerprints
• B. DNA copies
• C. Iris color
• D. Blood group

Answer 1

The Correct Option is A

When considering the characteristics of identical twins, it's important to understand the biological similarities and differences they share. Identical twins arise from a single fertilized egg that splits and develops into two embryos. This process results in them having:

• Same DNA copies: Since they originate from the same zygote, identical twins have identical genetic material, meaning their DNA is the same.
• Same Iris color and Blood group: Since both are determined by their genetic makeup, identical twins generally have the same iris color and blood group.
• Different Fingerprints: Despite having the same genetic material, fingerprints are unique to each individual. They are influenced by both genetic and environmental factors within the womb, such as different finger positioning, amniotic fluid pressure, and touch, leading to unique patterns.

Therefore, while identical twins share many physical and genetic characteristics, their fingerprints will not be identical. The correct answer is:

Fingerprints
