I'm consulting an FAQ in SPP but it doesn't really help.

I want a Miltank for the BF and caught one. Whoo. Anyway I want it with Heal Bell, but it learns Heal Bell at Level 53 and I was entering it into Lv 50. So I wanted to breed heal bell onto a baby.

Now this is what confuses me. Do both the mother and father need to have Heal Bell for the offspring to have it? Or if I bred a Male Smeargle (with Heal Bell) with a female Miltank (without HB) would the baby have it?

Thanks.
