I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
B) Bb x Bb because to have blue eyes they need to get the trait from both parents

Explanation:
Answer:
3 FACTS ABOUT PHOTOSYNTHESIS:
- The chemical equation for photosynthesis is: carbon dioxide + water --> glucose + oxygen
- Photosynthesis the process by which green plants and some other organisms use sunlight to synthesize (get or create) nutrients from carbon dioxide and water.
- Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Hope this helps!
