Exceptions to Mendel's Laws!!

* Incomplete Dominance...
- a BLEND of the two traits
examples: a pink snapdragon (red x white) ; wavy hair (curly x straight)

* Co-Dominance...
- where BOTH are expressed 100%...not a mix (think polka-dots)!!
examples: blood type; roan cattle (spotted)

* Multiple Genes...skin color, eye color, hair texture, heighth etc.

THIS SITE is a GREAT review for all the genetics stuff we've covered (& more if you want it!)
