Trihybrid (3 traits) instructional video on YouTube
Review how to complete a trihybrid cross or a cross between 3 traits. Do the genetics lab activity using the ear of corn provided for the purple and yellow cross and also do the link above for purple and yellow. Use the link above labeled purple and white for the purple and white cross. For red, purple, and white, do both links. Complete the Chi square for each. Then explain what might have caused any variation in the results of your ear.
Finally, look at the mystery ear, and using the genotype provided, see if you can hypothesis what cross might have produced this ear. Discuss your predictions and justify.
