Human Genetics
📋 What it is
Human traits and some diseases are inherited through genes; family history can reveal patterns.
🗣️ Coach says
Human genetics traces how traits and some conditions pass through families. Some diseases are inherited when a person gets certain gene versions; family trees can reveal the pattern. Understanding this helps doctors, but genes aren’t destiny — many traits also depend on choices and environment.

What did one nucleotide say to the other?
"We really need to bond — let's form a pair!"
😲 Whoa!
A family “pedigree” chart lets geneticists trace a trait through many generations — like a family tree for genes.
✅ Quick check: If a trait runs strongly in a family, what does that suggest?
Say your answer out loud first — then reveal.
That it may be inherited — passed through genes — though environment can also play a role.
Traits clustering in families suggest a genetic (heritable) component.

Draw a mini family tree and mark who shares a trait (dimples, attached earlobes). Look for a pattern.
