Can someone explain how you get a male maker vs. female maker?

Not sure if I got this right, so if you breed a male coral glow to a female non-coral glow the coral glow offspring will give mostly males...? And if you breed a female coral glow to a non-coral glow the coral glow offspring will produce mostly females...? And if you cross a coral glow with a coral glow the coral glow offspring will give 50:50...?

I think most breeders would agree that females are usually more desirable in most cases, males don't lay any eggs LOL. And you can pair one male to several females. So unless your male is really special you generally want females. But if you get a new morph, or a snake with a lot of genes, or a really expensive morph, then a male may be desirable since you can pass that gene on to as many females as fast as possible.
