Ok, the correct answer is C.Dominant and recessive, but let me explain why the other answers are wrong.
First of all, A and B are wrong because genes don't have color or size. They are just part of the blueprint the makes an organism.
Second, D is wrong because there's no such thing as negative or positive genes.
C is correct. Dominant genes will typically over power recessive genes.
Hope this helps! Merry Holidays!
