Marco and andre are twins. Which of these characteristics are they most likely to share

First off, we don't have any options.

They'd have a similar nose, eye color, hair color, and nail color (Just kidding.).

This is why fraternal twins run in families. However, only women ovulate. So, the mother's genes control this and the fathers don't. This is why having a background of twins in the family matters only if it is on the mother's side.
