Answer the following with a short solution if needed:
a. The gametes of a worm's genotype SsYy should produce what genotypes?
b. A genetic cross between two F1-hybrid rose plants having yellow petals will yield what percent green-petal plants in the F2 generation? Yellow petals are dominant to green.

children.

their children.
