When we look at family trees, or pedigrees, we can discover a lot about how traits are passed from parents to kids.
For example, take eye color. If both parents have brown eyes, it's very likely their children will also have brown eyes. This is all because of genetics!
Visual Representation: A pedigree chart uses shapes to show family members. Squares usually represent boys, and circles represent girls. Lines connect family members and show their relationships.
Generational Patterns: By examining the chart, we can see patterns. If a trait shows up in every generation, it might be a dominant trait. If it only appears sometimes and skips generations, it could be a recessive trait.
Understanding how these traits work can help us learn about inherited diseases. This knowledge allows families to make better health decisions. Pedigrees really help us uncover the mysteries of how traits are passed down!
