When we discuss dominant and recessive traits in humans, it's really cool to see how these traits are passed down in families.
Dominant traits are the ones that show up if you have just one copy of a gene. On the other hand, recessive traits need two copies of the gene to be visible.
Here are some easy examples:
Brown Eyes: If you get one gene for brown eyes (represented as B), you're likely to have brown eyes since this trait takes charge over lighter colors.
Widow’s Peak Hairline: This is the pointy shape some people have at their hairline, and it's a dominant trait.
Free Earlobes: If your earlobes hang down and are not attached to your head, that's a dominant trait. We show this as "F".
Blue Eyes: To have blue eyes, you need to inherit the blue eye gene from both parents (written as bb) because it is recessive.
Attached Earlobes: If your earlobes are attached to your head (shown as tt), this is a recessive trait, so you would need two copies of that gene.
Albinism: This is a genetic condition that makes a person have lighter skin and hair. It happens when someone has two copies of the recessive gene (aa).
It’s amazing how these traits can show up in families! One parent might have a dominant trait while the other has a recessive trait, leading to a mix of traits in their kids.
For instance, if one parent has brown eyes and the other has blue eyes, their child might end up with brown eyes if brown is the dominant trait. That’s the fun part about genetics!
