I don't remember this all that well but if I am thinking properly, it should be option C because Air is 2 oxygen molecules. That is what a homogeneous mixture is correct?
That the Red flowers are a dominant trait, and the white flowers would be recessive.
The Red Flowers are Homogenous Dominant
In a punnet square, The Genotype ratio for the red flowers would be 2:2
The phenotype would be 4:0
For the white flower
The Genotype would be 1:1
and the phenotype would be 1:0
The white flowers are Homogenous recessive
I think it is c but I’m not 100% sure so wait for someone else to answer too maybe ?
