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