Question

i have to do a chi square test based on the genetics of corn. I predicted that the ratio for the results below would be 8:2:2:1 and it works for the chi-square test. but then i have to say what the genotypes would be for each of the parents to match the ratio but i don't think any genotypes for parents would exist. did i do something wrong, what would be the real phenotypic ratio that I could get genotypes of the parent for?

Data:
yellow smooth kernels: 363
Yellow wrinkled kernels: 93
white smooth: 100
white wrinkled: 58
