Answer:
When a dominant trait joins with the recessive trait, only the dominant trait will show when determining the organism's characteristics.
Step-by-step explanation:
The dominant trait is "dominant" so it will mask the recessive trait. For example, brown eyes is a dominant trait for the color of someone's eye. Blue eyes is a recessive trait. If someone were to have both genes when they were born, they would have brown eyes because it masks the genes for blue eyes.
