While cruising the new posts I came across this one and can't really offer any help (even if I am a biologist). However, I just had to say it made my head spin and my eyes cross 😃 (I remember now, that's why I had a hard time in genetics class!).
haha ya i was like that at first. then i got into it a little more. maybe this other forum can help you, it helped me alot! 🙂 we are actually still going at it!
