1. Breeding Bunnies Lab

2. Background Information
Read the info and highlight/underline the trait that we are studying.
Does this trait provide high fitness or low fitness to the bunnies? Explain.
Low fitness
Bunnies die in the cold winter

3. Rabbits without and with fur
H = normal fur
h = furless hh
HH or Hh

4. Hypothesis #1 – Breeding Bunnies
If natural selection has a (positive) / (negative) effect on the fitness of bunnies with (fur) / (no fur), then (what will happen to the population over time??).

5. Hypothesis #2 – Breeding Bunnies
What will happen to the frequency (%) of H alleles and h alleles in the bunny population? State your hypothesis.
(hint: it starts out 50/50)

7. Sample Data Calculations
Gene frequency = # of alleles
total alleles
