When we look at families over many years, we can find some cool patterns of traits that get passed down. We often use family trees or pedigrees to show these patterns. Here are some important things to remember:
Inherited Traits: Some traits, like eye color or whether you have attached earlobes, can be seen in many family members over time.
Dominance: Some traits are stronger than others. If one parent has a certain trait, there's a better chance their child will have it too.
Recessive Traits: Other traits might not show up for a while. They can skip a generation and only come back if both parents carry the hidden gene.
For example, if both parents have brown eyes (which is a dominant trait), but their child has blue eyes (a recessive trait), it means both parents must have the blue eye gene hidden inside them. This way, looking at these patterns in genetics can help us learn about family traits over many years!
