GG, because both parents have the exact same gene which would cause the offspring to have the same gene.
<span>It will result in Negative frequency-dependent selection.
</span> Frequency-dependent selection is when the fitness of a phenotype depends on the frequency of the other phenotype in the population. In this case is negative frequency-dependent selection, because the fitness of a phenotype(pink) decreases as it becomes more common.
When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms wouldn't be able to compensate for the lack of carbon dioxide levels. Phototrophs wouldn't be able to produce their food in the form of glucose and hence wouldn't be able to respire too. That would result in lack of overall available food from phototrophs and lack of available oxygen for respiration.
Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is is released into the air and unused glucose is stored in the plant for later. That's why plants are so important to human and animal survival. Without photosynthesis we wouldn't have oxygen for food to stay alive and we would end up like the movie The Lorax
