3. Background Information
Evolution on a genetic level: A change in the frequency of alleles in a population over a period of time. Breeders of rabbits have long be en familiar with a variety of genetic traits that affect the survivability (fitness) of rabbits in the wild. One important trait is the one for furless rabbits (naked bunnies). The furless rabbit is rarely found in the wild because cold winters select against it.

4. While shaking, the rabbits are mating and you are mixing their alleles
What are we looking for?
In this lab:
Normal fur = F
Hairless = f
Take 10 seconds and shake up your bag of 50 red beans and 50 white beans!
While shaking, the rabbits are mating and you are mixing their alleles

5. Keep going until all of your beans are gone!
Remove 2 beans at a time without looking and record the data in your chart.
Put 2 red beans in your FF cup
Put 2 white beans in your ff cup
Put 1 red and 1 white in your Ff cup
Keep going until all of your beans are gone!
This is generation 1

6. Generation 2…
Put the beans from FF and Ff back into your back and shake it up! These bunnies have lived long enough to mate
Why do we not return the ff bunnies to the ‘mix’?
Repeat the process for generations 3-5, remember to record gene frequencies in your chart!
