"Tallness and dwarfness" in what species? Are we talking pea plants here? Horses? Humans?
If humans, do you mean just being on the short side, or do you mean actual dwarfism? If the latter, which kind? There are several different mutations that can lead to a form of dwarfism.
Communication: it's a two-way street, at least until someone invents mind reading.
The reason is due to how the genes function within the body, but it is a bit complicated, because not all genes work the same way.
"Different alleles can be dominant or recessive for different reasons. It all depends on the gene."
