Question

In corn, smooth kernels (K) are dominant to wrinkled kernels (k).

Answer 1

Heterozygous means 2 different zygotes. Since Smooth kernels are dominant, Zygotes KK and Kk will be smooth and kk will be wrinkled.

If you were to set up a Punnett Square chart like:

           K     k

   K   (KK)    (Kk)

   k   (Kk)     (kk)

the ratio for smooth to winkle would be  3 : 1

Which Will be 75% Smooth  and 25% Wrinkle
