Activity 2: Analysis of Indian Corn You will examine Indian corn purchased from the supermarket to attempt to determine the genotypes of the parents and the mode of inheritance. 1. Select an unknown ear of Indian corn: 2. Count the kernels by color and construct a table for your data below. 2 327 138 what phenotypic ratio do the data display? 1:2, t . ratio match any of the ratios we covered so far? If so, what is the mode of inheritance? If not, what mechanisms may have led to atypical results? Adtivits 3 Multi ene Predictons Now you will generate predictions for multi-gene crosses. 1. Say you performed the following cross in peas: where tall is dominant over dwarf (T gene), round is dominant over wrinkled (R gene), and yellow is dominant over green (Ygene) Determine the probabilities for the offspring phenotypes for each gene. 2. I gene tall dwarf Rgene Ygene round yellow green _ wrinkled 3. Make the following predictions: tall, round, yellow dwarf, wrinkled, yellow tall, round, green dwarf, wrinkled, green . .
