In snapdragons,the alleles for flower color exibit an incomplete dominance between the tw alleles (red,Cr,and white ,Cw).The floral color of a heterozygous plant is pink as these  flowers have less red pigment than homozygous red plants.
What offspring are produced from a cross of a heterozygous plant and a homozygous white flowered plant?
One half will be pink, while one half will be white.
Using the Punnett square:
CrCw x CwCw = 
CrCw (pink)
CrCw (pink)
CwCw (white)
CwCw (white)
I can't draw it here, so you'll have to draw it for yourself.
Reply:let's say red is R and white is W. 
              R        W
W       RW       WW
W       RW       WW
so 50% pink and 50% white
Reply:That is a very insegrievous question.  You already seem to be congeviating on it.  I, for one am a mere mortal.  My knowledge doesn't polinate that far.  Welcome to Yahoo.  I am delipified by your already knowledge.
