The correct answer is A at least one dominant gene from each parent.
In genetics, traits such as the white wings on a monarch butterfly typically depend on dominant and recessive genes. If a trait is dominant, it can manifest with just one copy of the dominant gene. Therefore, for the white wings to appear, at least one parent must pass on the dominant gene for that trait.
