In com, male sterility is controlled by maternal cytoplasmic elements. However, the presence of a nuclear fertility restorer gene (F_) restores fertility to male sterile lines. Using the following cardboard chips, simulate the crosses indicated below. Present your cross to your instructor for checking. After being checked, draw your simulated crosses in the spaces provided below. Give the genotypes and phenotypes of the offspring in each cross, and properly label the nucleus and the cytoplasm of each individual in the crosses. Big white circular chips Male sterile cytoplasm Big peach circular chips Male fertile cytoplasm Small peach circular chips FF nucleus Small half-white-half-peach circular chips Ff nucleus Small white circular chips ff nucleus a. male sterile female x FF male Explain your results. b. male sterile female x Ff male Explain your results.
