Lab 8: Genetics of Corn Lab and Journal Worksheet
Genetics of Corn Lab
Instructions: Answer the questions below, based on Experiments 1 - 2.
Experiment 1 - A Monohybrid Cross
Complete the Punnett square for a cross between two heterozygous purple kernels, Pp
What percentage of offspring do you predict will be purple?
What percentage of offspring do you predict will be yellow?
Count the purple and yellow kernels in 5 rows of corn kernels for Corn #1 and complete
the following table:
Number of Kernels Observed
Number of Kernels Expected
Total number of kernels observed: 156
To calculate the number of kernels expected, multiply the total number of kernels
observed by the percentage of kernels you predicted would be purple. Then multiply the
total number of kernels by the percentage of kernels you predicted would be yellow.
example, if you predicted 50% of your 150 kernels would be purple, your number of
