need a little more help?

Question

i posted that i need to know how to set up a trihybrid cross with Tt Yy Rr Bb but now i have it setup does each square have 8 letter to a box? like TTRRYYBB?

Answer 1

Yes. Be sure you keep pairs of letters together (both t's, both r's, ...)

Answer 2

That's not a trihybrid cross. Tri = 3. You have 4. Yes, though, each square would have 8 letters (2 alleles for each gene)
