The answer is polygenic inheritance.
Polygenic inheritance is responsible for traits that are controlled by two or more genes. It is also called multiple gene inheritance. Examples of polygenic inheritance are height, weight, skin color, eye color.
Since a great number of genes control one trait, it is expected that each one has<span> a relatively small effect</span>
Answer:
A
Explanation:
I believe the answer is A. One is polar and One is non polar. H20 is the polar one. Polar beans there is a charge to it and the bonds are unevenly distributed. Since the hygrogen molecules are negatively charged, they make it polar. This is why water can mix with salt and stuff. O2 is non polar because the bonds are equal. There is a even distribution of electrons between the two oxygens so it has an even balance. This causes it to be non-polar.
That is why I think it is A
Yes I this that is what I shall call a period
