In this lab, the genotypes and phenotypes of corn and soybeans were studied. This lab aimed to observe phenotype ratios and Mendelian inheritance patterns. Each lab section was given approximately one hundred heterozygous (G/g) corn seeds for the corn study to plant and grow over the course of a few weeks. The allele for a dominant green color was noted as “G” and the allele for a recessive white color was noted as “g”. The recessive white phenotype results from the plant having an absence of chlorophyll, making (g/g) a lethal allele as plants cannot live without chlorophyll to absorb sunlight. The corn sprouts that carry the (g/g) allele will not be able to live long after breaking through the soil. The corn data was found to have the predicted green to white ratio of 3:1, a Mendelian ratio. The null hypothesis for this study was accepted through a P-value = 0.05 Chi-Square analysis. For the soybean section of the lab, heterozygous (C^G/C^Y) soybean parent plants were crossed and allowed to grow for a few weeks. The allele for a dominant green color was labeled as (C^G) and the recessive yellow allele was labeled as (C^Y). The ratio of offspring was expected to be in a 1:1:2 ratio of green to yellow to yellow/green, with yellow/green being the expression of incomplete dominance. The observed green to yellow to yellow/green ratio was 2:4:5, not a Mendelian ratio but it is a result of the incomplete dominance. The null hypothesis for this study was rejected through a P-value = 0.05 Chi-Square analysis.
