If you have a dihybrid cross of a pea plant for the following two traits: R = round, r = wrinkles (Round (R) is completely dominant over wrinkled (r)), and V = violet flowers, v = white flowers (Violet is completely dominant over white). What is the probability of getting a plant with Round peas and white flowers from the following cross:   RrVv  x   rrVv    

BONUS QUESTION:  Up to 4 EC pts. Many photosynthetic organisms carry out a process known as cyclic electron flow (also known as cyclic photophosphorylation). Given your knowledge about the Calvin cycle and about what happens in cyclic electron flow, explain: Be sure to answer both parts (a and b) and start your answer with an indication of which part you are answering.    (a) why it is beneficial for the plant to undergo this alternative route in electron transfer  (2 pts), (b) Why can’t the cell continuously use this cyclic mechanism of photosynthesis in order to always conserve water? In otherwords, why must all plants do linear photosynthesis sometimes?  (2 pts)
