Mechanisms of evolution poster

You will be working in Pairs A’s and B’s will be creating a poster on BottleNeck Effect C’s and D’s will be creating a poster on Founder Effect

To start out… You will use beetles for your poster. Your initial population must include 10 homozygous dominant individuals 7 heterozygous individuals 3 Homozygous recessive individuals The dominant trait is Blue body color The recessive trait is orange/red body color

What needs to be on the poster? Name of the type of genetic drift Must show initial population Draw and color all the beetles Must include labeling alleles for each beetle The bottle neck or founder effect event For example: show the earthquake The new population

Once you finish the poster Now write a story explaining what is happening on your poster Calculate the allele frequency for the initial population Calculate the allele frequency for the final population Has your population evolved? How do you know?
