What are the expected ratios of any monohybrid cross? What are the expected ratios of any dihybrid cross?

Monohybrid - assuming you start with homozygous dominant x homozygour recessive and T=tall, t=short
TT x tt ...F1 = all Tt  (all tall)...F2 = 1TT : 2 Tt ; 1 tt (3 tall : 1 short)
Dihybrid - assuming you start with homozygous dominant x homozygour recessive and the genes being considered are not on the same chromosome (where A is blue flowered and a is white, B is green leaf and b is striped)
AABB x aabb  or AAbb x aaBB will produce
F1 = all AaBb (all blue flower green leaf)
F2 = 9 blue green ; 3 blue striped : 3 white green and 1 white striped.

Of course there are so many other starting points in these crosses that it would take pages to list all possible outcomes, but at least you have a start here.
