Several biology students are counting kernels in an ear of corn. They count a
total of 420 kernels: 242 purple wrinkled, 84 purple smooth, 70 yellow wrinkled, and 24 yellow smooth.

What is the best ratio of kernel phenotype in this case?
A) 3:2:2:1
B) 8:4:2:1
C) 9:3:3:1
D) 24:8:7:2

This ration cannot give us the exact number of kernels that will be produced and it will also not be able to tell us the exact number for each type of kernels. But it is nearest to the values.

Moreover, if we divide all the ratio's with the smallest number i.e 24 we see that the values are closer. For example, 242 divided by 24 gives 10.1 which is near to 9.
