Here is a website that has a bunch of practice problems on it. You will want to skip the trihybrid (although you might have fun trying it) and skip linked traits. Do the sex-linked traits and then stop unless you have time to spare. The link is http://biology.clc.uc.edu/courses/bio105/geneprob.htm
Another link you might find useful is Khan Academy Genetics For our class purposes I would focus on the introduction, punnett square fun, and sex-linked traits.
Mrs Hertel's video is below. I will be uploading the video to youtube but internet connection is poor. Will have it up in the morning.
