Answer 1

Breeding for specific traits may trigger unwanted, even dangerous, genetic side effects.

The more one narrows down the sire selection, the more, and the more diverse, mares must be kept in order to retain the original genetic variation. The most efficient way to maintain diversity is to use multiple sires on several small sets of mares, and rotate the sires. The idea, always of course influenced by real-world considerations, among them the phenotypic suitability of a particular combination, is to equalize breeding opportunity in order to maximize the proportion of genes retained.

Answer 2

Crossbreds arnt all bad. I have two crossbred mares who are excellent riding mounts. But usually when xbreeding, you get a horse with bad conformation. It has the build of both horses which sets it off balance. Also, if one of the horses had a pedigree, it doesnt look good if that horse has a xbred foal.

Answer 3

nothing really. Breeding true to a breed means you'll end up with more predictable results. But, cross breeding can give you a better result if current breeds are not what you're looking for. This is being done quite a bit with sport horses where they are crossing breeds looking for a better performer.

Answer 4

If u crossbreed a horse it might mess up their whole pedigree and might mess up there looks and strength and could be like with long legs and have a short neck
