Photosynthesis could be said to be a manufacturing process usually associated with green plants. It involves different processes and elements necessary for the transformation of light energy usually derived from sunlight. The green pigment of plants called the chlorophyll offers them the ability to absorb Radiant energy from the sun which is then converted into chemical energy forming energy-rich compounds including water, minerals and carbon dioxide. Photosynthetic activity is usually represented by a general formula; which goes thus;
As you see on the table, there are 3 ways the offspring can get the dominant trait. RR, Rr, and rR (order was switched for clarification). There are 4 total outcomes. In this case, the problem can just be treated as a probability question.
3 out of 4, or 3/4 * 50 is 37.5, which can be rounded to D. 38.
