Hi! Like any good scientist, I'm going to go ahead and cite the sources that I plan to be using.
Introduction to Genetic Analysis, Ninth Edition, Griffiths, et al. - This is where most of the diagrams in the explanations I have will come from, as well as some of the background knowledge about genetics.
Wikipedia - even though it's not the greatest source, I trust it for general, broad-strokes sort of information. Also, I'll be linking to it throughout the explanations.
http://hopes.stanford.edu/ - This website, for the The Huntington's Disease Outreach Project for Education, at Stanford, really helped me to break down and understand some of the more complicated concepts surrounding Huntington's.
