1) The first reactant is incomplete.
2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.
3) The general chemical formula of the alkanes is
4) Hence the equation is:
5) The name of the alkane is propane, so the word equation is:
propane + oxygen → carbon dioxide + water
6) The equation is unbalanced. This is the balanced equation:
7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.
8) This kind of reactions release a lot of energy.

Explanation:
Answer;
-Polygenic inheritance
Explanation;
-Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect.
-Examples of polygenic inheritance in nature can be found in many places: in human height, skin color, and hair color; in animal size, longevity, or disease resistance; and in plants with grain color, length of maize, or flower size. All of these traits are influenced by multiple genes and considered polygenic.
