Muddiest Point!

Hey guys, I think I pretty much get everything, but now that we've learned so many different crosses, I'm getting kind of confused as to when I use the X's and Y's and when I use ex: IaIa in problems and when I use ex: Ff or ff as answers or variables in problems.

  1. you use X and Ys when it is sex linked. So determing or something with a gender. :)
    hope this helped!
