AP Biology
Unit 6: Genetics
Be certain you remember your genetics vocabulary! Use the word study tools (flash cards) available in the
MasteringBiology study area under genetics.
If you need more practice with the genetics topics for days 2-4, check the Honors Biology Genetics unit on
Weebly for full problem sets. If you need help, PLEASE come in before or after school so we can work together.
I will also make a key available so you can check you work for accuracy.

day 9: DUE: Online HW
Ch.11, 12 Test: 40 questions, lab quiz
Butterflies have an X-Y sex determination system that is different from that of flies
or humans. Female butterflies may be either XY or XO, while butterflies with two
or more X chromosomes are males.
This photograph shows a tiger swallowtail gynandromorph, an individual that is
half male (left half) and half female (right half). Given that the first division of the
zygote divides the embryo into the future right and left halves of the butterfly,
propose a hypothesis to explain how nondisjunction during the first mitotic
division might have produced this unusual-looking butterfly.
