Which describes the matting of organisms that have different homonogenous allelies for a single trait?

The Dobzhansky-Muller model suggests that divergence among alleles at different gene loci leads to genetic incompatibility between species. Why is genetic incompatibility between two alleles at the same locus considered less likely?

Because reproductive incompatibility many involve many more genes than just one

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
