The AP Biology students had their quiz on the material from Chapter 15 stuff. Nondisjunction, sex-linked traits and recombinants were the subjects of the quiz. Afterwards, the students met in their fly groups (which means both cool and fruit flies) and predicted what the F2 flies should look like. Get it?
The Chemistry students finished their review of the material from Unit 3, Chemical Bonding. Stuff like electronegativity, nonpolar covalent bonds and valence electrons were discussed calmly and maturely.
