Drosophila Lab begins and Rock Lab tomorrow!

AP Bio - Drosophila Lab begins ...

Both AP Biology classes started their Drosophila Lab today.  Third block is working with sex-linked white-eyed mutants while fourth block has the apterous wing mutant.  We ordered F1 flies so all we have to do are sort males and females, prepare culture tubes and distribute the flies.  Our F2 flies should be ready to sort and count in about two weeks.  Above, some serious sorting with the aid of a hand lens.

For data we collected during our genetics class last fall, we did a Chi Square analysis.  Tomorrow,  we wrap up genetics and head on to Crick's Dogma - Replication / Transcription / Translation.

In Selected Topics, we are continuing 7 Days of weather.  Also, tomorrow we have our Rock Lab with density calculations.  Today, we worked on plate tectonics, convection and the USGS website.

Today was Valentine's Day ... a barrage of flowers to the high school last block.
