Pedigrees are one of the more challenging concepts to wrap your head around in genetics. The basics of pedigrees, what the symbols and charts represent are easy, however interpreting and creating the pedigrees from a description can be quite the task. Today in class students tried their hand at pedigrees not just with pen and paper but with Swedish fish and gummi bears. The fish were "female" and the bears were "boys" and by reading about the family history, students were able to assemble pedigrees using their candy to represent the family members, with their color(s) representing their genotype.
Tomorrow's quiz is over genetics vocabulary, punnet squares, incomplete and co-dominance, with an extension problem about dihybrid crosses. Use the videos below to help you study for the quiz.
