A cross between two nematode roundworms, one that moves normally and one that rolls in circles, results in 50% offspring with normal motion and 50% offspring that roll in circles. A.  Predict the genotypes of the parent worms. (2 points) B.  Explain your reasoning.  Include a Punnett square (use the “insert table” function) that supports your prediction (4 points).
