First Fly Count and Evolution ...

Today in AP Biology, we checked some homework then sorted and counted our F2 flies.  First block students are working with a X-linked mutant, white eyes and the second block students are working with the autosomal mutant, apterous wings.  We had time to review gene regulation ... lac and trp operons and eukaryotic gene regulation (transcription factors, TATA box and enhancers/activators).  We ended the class starting our study of evolution ... starting with Darwin and Wallace and proofs of evolution (fossil record, embryologic evidence, molecular evidence and more).  We will continue this on Thursday, adding some Hardy-Weinberg problems.

In fifth period computer programming, we will be finishing our farm scene with animation and music!

I got home late ... checked on Granny before coming home to grade papers.
