A dominant trait is like the favorite toy that always wins when you play with your friends.
Imagine you and your friend each bring a toy to school. You bring a red car, and your friend brings a blue truck. When you all decide which toy is the best, the red car gets picked more often because everyone likes it better, maybe it goes faster or has cooler lights. That means the red car trait is dominant in this game.
Like a Superpower
Think of a dominant trait like a superpower that makes one thing stand out over others. In real life, when you have a dominant trait, it’s like having the best crayon for coloring, everyone notices it first. For example, if your mom has curly hair and your dad has straight hair, but you end up with curly hair too, that means curly hair is the dominant trait in your family.
It Doesn’t Always Win
Just because something is dominant doesn’t mean it always wins, sometimes the blue truck might be picked just for fun. But most of the time, the dominant trait is the one people remember and choose first.
Examples
- A brown-eyed parent and a blue-eyed parent have a child with brown eyes. The brown eye color is the dominant trait.
- When a plant with red flowers is crossed with one with white flowers, most of the offspring have red flowers. Red is the dominant trait here.
- If you inherit one copy of a gene for curly hair and one for straight hair, your hair will be curly because curly is the dominant trait.
