remember the passage about phenotype being determined by the mother? what did everyone put for these questions-
1. why does the larvae have brown eyes and then red at adulthood? i put that the pigment k-something is in the oocyte.
2. what happens when brown males and brown females mate? well the problem is that it wasnt clear whether this was a BB x Bb or Bb x Bb or Bb x BB cross. I assumed it was Bb x Bb...as this created a perfect answer choice. Of course, all larvae are brown initially (since the mom is). If it was Bb x Bb...1/4th will be red in adulthood. If its BB x Bb or Bb x BB, 1/2 will be red in adulthood.
