Today in class I did a reading check by asking students to define and give examples of:
complete dominance, codominance, incomplete dominance, pleitropy, epistasis, polygenic inheritance.
We then had a discussion of the last three terms using the examples of Marfan Syndrome and cystic fibrosis for pleiotropy, albinism for epistasis, and height and skin color for polygenics.
We ended by looking at the pedigree for hemophilia and having a quick discussion of its impact on history.
No homework tonight. Enjoy it.
