Sample Question
What does it mean for a trait to be dominant?

Dominant traits are always physically stronger than recessive traits.

A dominant trait will always express itself in an organism whether it is partnered with a different (recessive) trait or with another dominant partner. For example: The tallness trait in peas can be recognized as "A" which is dominant and the recessive shortness can be recognized as "a" "AA" will result in a tall pea as will "Aa"

An organism can have multiple dominant traits at the same time.

A dominant trait will only express itself if it is partnered with another dominant trait.
