What offspring are produced from a cross of a heterozygous plant and a homozygous white flowered plant?

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
