Ever wondered how we know if a genetic cross experiment fits Mendelian ratios? It's like trying to guess the secret recipe of a dish just by tasting it. This is where chi-squared tests come to the rescue!
In a chi-squared test, you have
H0 (Null Hypothesis): Everything is as expected; no surprises! It's like your mom telling you to clean your room, and lo and behold, it's already clean.
🌍 Real-world example: In a genetics test, if you're expecting a 3:1 ratio, this hypothesis says, "Yep, it'll be 3:1."
H1 (Alternative Hypothesis): Something fishy is going on; the results are not as expected. This would be like finding a sock in your soup 🧦🍲.
🌍 Real-world example: In the same genetics test, this hypothesis says, "Nope, it's not gonna be 3:1. Something else is up!"
🌍 Real-world example: Bateson in 1901 tested chicken feather and comb traits. He found out that they fit the expected 9:3:3:1 ratio! The genes were indeed unlinked, just like your Wi-Fi when it goes off at crucial times.
