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
