well as far as i know, monohybrid is just when there is one characteristic, so u get like A as dominant, b as recessiv. dihybrid is where there are two characteristics so u can get AaBb in one gene.
The gametes of AaBb will be AB, Ab, aB, and ab
if u cross 2 of these together, its basically the same thing as monohybrid, where u use the punnett square, but its a lot bigger
i think thats right...anyone else?

that's dihybrid inheritance because it's inheritance of 2 genes therefore 2 characteristics... Aa (1st gene) Bb (2nd gene)
monohybrid inheritance is inheritance of 1 gene therefore 1 characteristic
