Explanation / Answer

It should be like this I think: I'm assuming that one of the traits (red or axial) is dominantwhile the other is recessive. Since one of the offspring's trait is dominant and one isrecessive, it should go like this: 3/4 for the dominant one and 1/4 for the recessive one. 3/4 x 1/4 3/16 3x100/19 = 18.75, which is almost 19.
