When learning about dominant and recessive traits, real-life examples can help us understand better! Let’s take a look at a few simple examples:
Pea Plants: A scientist named Mendel studied pea plants a long time ago. He found that purple flowers are a dominant trait, meaning they show up more easily. We can call this trait "P." On the other hand, white flowers are recessive and are called "p." This means only plants that have two "p" genes will have white flowers. So, if a plant has "PP" or "Pp," it will have purple flowers. Only "pp" plants will show white flowers.
Human Eye Color: Eye color in people is another good example. Brown eyes are dominant, which we label as "B." People with the "BB" or "Bb" gene will have brown eyes. Blue eyes are recessive and are marked as "b." So, only people with "bb" will have blue eyes.
Freckles: Freckles are an interesting trait too! The gene for having freckles is dominant and we call it "F." The gene for not having freckles is recessive, which we label "f." So, if someone has "FF" or "Ff," they will have freckles. But only those with "ff" will not have any freckles.
By looking at these examples, it's easier to understand the difference between dominant and recessive traits. They become simple and relatable!
