in plants smooth seed coat is dominant to wrinkled and yellow is dominant to green. a plant hybrid for both traits is crossed with a plant that is hybrid smooth and green.

What are the genotypes  of these plants?

Hi callie
We have to set up a code first
  Let S = Smooth
      s = wrinkled

      Y = Yellow
      y = Green

  Cross is SsYy   x  Ssyy or
         SsYy   x SSyy  It depends upon whether or not this plant is homozygous or heterozyous)
 Both SSyy an Ssyy are smooth and green

Were you asking about the Genotypes of this cross?
Do you know how to set up a Punnet square  to do this?

If not get back to me
