Question
I have to do a trihybrid cross for science ,but i dont know how to set up and figure out the punnett square for it. I chose for the male to have horns(H) no wings(g) and fire(f). the female to have no horns(h) wings(G) and fire(f). can u help?
Hi Completely: WOW, nobody does trihybrid crosses. Even in my college genetics classes, I only give dihybrid crosses. Are you sure you got the instructions right? That it's not a mono- or dihybrid cross through three generations? What grade are you in?
Let me know ASAP and I'll help you. I understand why you're confused!

OK, scratch that. I just did a quick internet search and found this:

Scroll down to find the trihybrid cross example. I still think it's overkill.
