While you are roller-blading around Lake Artemesia in Greenbelt, you notice a fascinating bark beetle on the trees. Glad for an excuse to catch your breath, you stop and observe that there are three different feeding behaviors in these beetles and you record the ratios of beetles with each of these behaviors. Being the biologist that you are, when you get home you dive into the literature and find the following genotypes are in the beetle population.  BB  (feeds under bark)      0.7  Bb  (feeds on top of bark)  0.2  bb   (feeds on leaves)        0.1  What are the allele frequencies and expected genotypic frequencies? Explain.

While you are roller-blading around Lake Artemesia in Greenbelt, you notice a fascinating bark beetle on the trees. Glad for an excuse to catch your breath, you stop and observe that there are three different feeding behaviors in these beetles and you record the ratios of beetles with each of these behaviors. Being the biologist that you are, when you get home you dive into the literature and find the following genotypes are in the beetle population. 

BB  (feeds under bark)      0.7 

Bb  (feeds on top of bark)  0.2 

bb   (feeds on leaves)        0.1 

What are the allele frequencies and expected genotypic frequencies? Explain.
