Genes are the segments of DNA transferred from parents to offspring
It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
Hydrogen bonding, ionic bonding, dipole-dipole interactions, and London dispersion forces!
So basically you will have to label the purple parent 1 and whatever gene that is then the same for parent 2 here is an example of a punnet square so maybe you can understand better
They are made up of nitrogen bases,sugars,and a phosphate group
