The resources here are terrific and I plan to use some of them in my own class!
A lot of my students already have record of their family pedigrees, which is awesome.
Based on the students' pedigree, some of the topics that they discuss are: dominant/recessive alleles, codominance, inheritance, genetics, Mendel's genetics, phenotype, genotype.
They then have time to think and research traits that are dominant and recessive, and relate those traits to themselves.
From there, I have the students choose one trait (or two) traits and have them 'backtrack' to the origin of the trait, as far as they can go.
Good discussion topics from this are:
Why do you think cats have such different fur patterns?
Why do traits appears and disappear throughout your family line?
Where did your trait originate from? What ethnicity?
What traits do you think are dominant/recessive/codominant and why?
When thinking of the health industry (or your own personal health) why is understanding genetics so important?
Have students research and report a real genetic disorder.
Have a professional genetic counselor talk to the students.
Future possibilities through understanding genetics.
