What would happen if a morning dove

What would happen if a morning dove had babies with a ring necked dove?

Could this make the babies un-natural, like could problems ocure with breeding them because this person wanted to do this with his birds, he wanted some pretty doves that no one else could have.

I have seen a photo of a part morning dove & part ring neck dove but it looked pretty much like a morning dove to me.

Species often cross breed in nature. Right here in North America, Pin Tailed ducks and Mallards regular cross breed. Many species of grouse will cross breed as do wolves and coyotes where their ranges meet. Whales will mate across species as well. There's been several sightings of spotted and bottle nosed babies. Killer whales have been found with part pilot whale babies. Most of these crossings are infertile and if they are, the males are almost always infertile. Some hybrid parrot hens can produce offspring. The red factor and apricot canaries are the result of fertile crossings between the red headed siskin and the wild canary :-) . Most crosses are really neat to look at. I love looking at Catalana macaws which is a hybrid between two large macaw species.

More than likely your birds would have no problems producing offspring but the offspring won't be able to breed. When they hit sexual maturity they'll be a mix of the two species mating styles. Same with their colors. A Female hybrid will share the same female colors of both species. The males will do the same. Some hybrid partridges will do all the dancing and thrumming of their dad but will toss in vocal calls of a male of their mom's species. It gets pretty weird!
