It depends if the dam carries a coat factor. If she doesn't, none of them should be coats. If she does, then you have a 50% chance that a pup would be a LC.
You can tell very young if they're going to be coated or not. The breeder should know enough to tell you which ones are standard and which ones are coated. The biggest sign is the ears, they'll have longer hair coming out of them and around them.
Sex has nothing to do with it. Just because the father was LC doesn't mean only the boys have a chance of being LC.
