Once again, Khan Academy is here to make life easier! This is a nice lecture introducing you to heredity, which is basically what we learned this chapter. It starts at the beginning with the basics, like physical traits, and goes into homozygous and heterozygous as the video goes in. The video goes into dominant and recessive traits, and also touches on the different types of dominance there are, i.e. codominance. The video uses proper terminology like allele, homozygous, heterozygous, dominant, recessive, etc. The video also goes into Punnett Squares.
Ok so here's another nice video! Basically, the guy has a pedigree and is trying to figure out what type of disease is present in the family. He takes you step by step in eliminating choices and deducing what kind of disease is present in the family. Instead of looking at the pedigree as one big thing to figure out the disease, he goes step by step through the generations, which is different from what many people do. Being as though DWebs has asked questions using pedigrees, it would make sense for us to see this on the exam, so this would be a great help! Wait, you're probably gonna read this after the exam... Oh well...
