I know of several gaited Morabs where the dams are
50/50 ungaited morabs and the sire is a strongly gaited Morgan. As a matter of
fact I think most of his get is gaited no matter what he's bred to.
I have heard that too...that if one wants a gaited half Arab (or a gaited
horse that his half non-gaited), then to make sure that the gaited parent is
the mare for the greatest chance of getting gait. I've known of 6 horses
that were half of a gaited breed (2 Arab/Paso Finos, 2 Arab/TWH, 1 Morgan/MFT,
and 1 Arab/RMH). All were gaited, and in all cases, the dam was the
gaited breed. Of course, we need some examples the other way, with the
gaited parent beng the sire, to see if "the rule" works. <G>
