The majority of the human body is made up of molecules that contain H, C, O, N, and P. Where do we get these elements, and how are they able to sustain life?

See the answer below

Explanation:

1. This is an example of monohybrid breeding. A monohybrid breeding is the type of breeding that involves parents with a pair of contrasting characters. On the other hand, a type of breeding involving a single gene is what is known as monohybrid breeding.

2. When a red flower snapdragon is crossed with a white flower snapdragon, the resulting offspring are usually pink - an indication of incomplete dominance of the gene responsible for flower color. Assuming the red flower's genotype is AA and that of the white flower is aa:

                       AA      x      aa

                 Aa      Aa      Aa      Aa

F1 genotype = all Aa

F1 phenotype = pink flower

At F2:

                          Aa      x      Aa

                 AA         2Aa           aa

F2 Genotype/phenotype:

       1AA - red color

       2Aa - pink flower color

        1 aa - white flower color.
