      A plant with genotype SsYy is crossed with a plant with genotype ssYy. S (spherical seeds) and Y (yellow seeds) are dominant over s (wrinkled seeds) and y (green seeds), respectively. The genes for pea colour and shape are on different chromosomes and therefore inherited independently. Using a Punnett square, predict all the possible F1 genotypes. ( please imagine them in a square)

      How many of the resulting genotypes have a phenotype with wrinkly green seeds?

      AM i RIGHT IN SAYING THERE WOULD BE 2 WITH WRINKLY GREEN SEEDS i’VE PUT A STAR by the two i believe to show this i BELIEVE SHOW THIS

      Two of how many? You should show your result as percentage.

      The second plant can make only sY and sy gametes, so it doesn’t make sense to use it twice in the square.
