how would i make a punnet square to find the offspring of parents:
SsYy x ssyy
I don't understand what i would put for each of the boxes on the outside
across the top
sy sy sy sy
one parent is Ss Yy
so put those two across the top
-- Ss Yy
across the top and bottom.
Wouldn't the top be the same as the bottom? According to this genotype, the ratio will be 1:1:1:1
