Is to photosynthesis as is to cellular respiration?; How are photosynthesis and cellular respiration related in oxygen?; In which process cellular respiration or photosynthesis is oxygen a reactant?; What is oxygen to photosynthesis?
Cellular respiration is the process by which glucose is broken down into simpler compounds in order to release the stored energy.
The final electron acceptor in aerobic cellular respiration is oxygen. Photosynthesis produces glucose and oxygen, which are required in cellular respiration.
Photosynthesis is the process by which carbon dioxide and water are converted into oxygen and glucose. The plant consumes glucose as food and produces oxygen as a byproduct.
Cellular respiration is the process through which oxygen and glucose are converted into water and carbon dioxide. Water and carbon dioxide are byproducts of the process, while ATP is the energy that is produced.
During photosynthetic electron transport, oxygen (O2) is produced when water is divided by the oxygen-evolving complex to deliver protons and electrons to the chloroplastic electron chain, resulting in the production of ATP and NADPH—the energy source and electron transporter.

Environmental elements like diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all affect which genes in an animal are expressed, which in turn affects the animal's phenotype.
There are two categories of factors that are known to affect phenotypic diversity in a population: genetic and environmental. Sometimes a gene's DNA sequence or level of activity is altered by the environment. Either of these outcomes can alter the proteins that come from a gene, which in turn affects traits. The nucleotide sequence of a gene can be altered by some hazardous environmental factors. For instance, UV radiation has the ability to damage DNA strands.

The non-Mendelian inheritance that states that neither trait is dominant and the traits appear to blend together is called incomplete dominance.
The non-Mendelian inheritance pattern that states that neither trait is dominant nor the recessive is codominance. Incomplete dominance is the phenomena when a dominant allele is unable completely mask the features of a recessive allele due to which the organism results in a physical appearance which shows a blend of both alleles equally. For example, the case of pink flowers in Snapdragon.
