Critical Thinking Activities - Chapter 11

Question 1. Consider the proposal that handedness is inherited with right-handedness dominant (RR, Rr) and left- handedness recessive (rr). Of all the possible combinations of parents and offspring by phenotype, what combination of parents and offspring would cast doubt on this simple hypothesis?

Question 2. Corn has 10 pairs or 20 total chromosomes. If Mendel chose corn instead of pea plants to conduct his first experiments, what is the maximum number of traits he could have documented in breeding experiments in order to establish his law of segregation (each trait is determined by two factors) and independent assortment (the factors assort independent of other factors)?

Answers are available to instructors in the Instructor's Manual.
