Answer: The reactants for Photosynthesis are the products for Cellular Respiration and the reactants of Cellular Respiration are the products of Photosynthesis.
Photosynthesis:
6CO2 + 6H2O -> C6H12O6 + 6O2
**6 Carbon Dioxide + 6 water -> Glucose + 6 Oxygen**
Cellular Respiration:
C6H12O6 + 6O2 -> 6H2O + 6CO2 + Energy
**Glucose + 6 Oxygen -> 6 Water + 6 Carbon Dioxide + Energy**
Well firstly, alleles are different versions of genes. A dominant allele will show it's trait regardless of if the organism only has one copy of the allele (heterozygous). A recessive allele will show the effect only if two copies of the allele are present (homozygous)
