Why don't identical twins have the same fingerprints?

• They have different DNA from birth.

• Environmental factors during development cause differences.

• They are not actually twins.

• Fingerprints are determined by diet.

What analogy is used to explain how the same DNA can lead to different outcomes?

• Making pizza dough

• Building a house

• Growing a plant

• Baking a cake

How does the environment influence the development of identical twins?

• It makes them identical in every way.

• It has no effect on their development.

• It affects how their DNA is expressed.

• It changes their DNA structure.

What factors in the womb can lead to differences in identical twins?

• Different exercise routines

• Different sleep patterns

• Different diets

• Different blood pressures and hand positions

How does DNA change over time in identical twins?

• It changes only if they live in different environments.

• It remains completely identical.

• It accumulates small, random mutations.

• It becomes more similar.
