I said it never.. and will say it now..
What is the hardest thing they had in Genetics... did they have chromosom Mapping.. NOOOOOoo.. They had simple family trees, crossing xy by x'y' and some co-dominance.
Let see for phy... Cardiology, Hematology, Muscle, Hormones, Blood sugar, nervous system.... Plus a lot of it was experiment questions. Something I incountered in my Physiology class... not so much in Genetics. ( BTW... I like my genetic course as well.. maybe take both).
