Hey there future biologists! Get ready to dive into the mind-boggling world of allele frequencies, Darwin, Mendel, and PINK FLOWERS! 🌺

Darwin's Theory of Natural Selection 🐦

Darwin Says: If you've got the traits to survive, you're gonna make more babies! 🐣

 

Real-world Example: Imagine you're a bird with a beak that's PERFECT for picking berries. More berries = more food = more baby birds. Your beak trait passes on. Congrats, you're a winner in the game of life!

Mendel’s Magical Pea Plants 🌱

Mendel Says: Traits aren't a blend of Mom and Dad; they come in distinct units called genes!

 

Real-world Example: Think of your genes like a deck of cards. You get half from mom and half from dad. You can't have a half-Queen and half-10 card; each card (or gene) is distinct!

Weismann's Germ Plasm Theory 🧬

Weismann Says: Your muscles from weightlifting won't get passed down to your kids. Sorry, Arnold Schwarzenegger!

 

Real-world Example: If you dye your hair purple, your future babies won't be born with purple hair. Traits are inherited through sex cells, not somatic (body) cells.
