Refer to the figure showing the Dobzhansky-Muller model of the evolution of reproductive isolation. The F1 hybrids between the species at the end of this process have reduced fitness.From this, we can conclude that
A) the combination of a single A and a single B will reduce fitness.
B) the combination of a single a and a single b will reduce fitness.
C) BB will have low fitness irrespective of the genotype at locus A.
D) individuals that are AA will have low fitness irrespective of the genotype at locus B.
E) individuals that are bb will have low fitness irrespective of the genotype at locus A.
