Question:
I am teaching middle school genetics to my group of honors science students. We are working on Punnett Squares completing trihybrid crosses and what

I am calling quadhybrid crosses (16 x 16). My question is this-- What do you call a cross with 4 characteristics? I can find no place on the internet that shows sample problems called "quadhybrid".


Replies:
It is a multihybrid cross. It is most easily computed using the algebraic system for determining the outcomes rather than the typical punnett square method.

I don't think most classes go this far-thus no mention of the process anywhere. But if three traits are called trihybrid, I think tetrahybrid would be the next logical step.
