If a total of 1250 offspring were obtained from your cross, determine the number of offspring that you would expect to obtain that represent a single crossover event between pr and vg if interference does not occur. express your answer as a whole number.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
