Biology gene question
I'm a bit confused here, Flood.
Okay, so I was studying Biology by doing a practice multiple choice test. I came up to a question which goes like this:
[u]If short hair in dogs is dominant, then[/u]:
A. Mating of Short haired dogs would produce only short haired offspring.
B. Mating of Long haired dogs would produce only Long haired offspring.
There were two other options, but forget those.
I picked A, but B was the correct answer. I don't get it, shouldn't the mating of two animals with a dominant gene always produce offspring with that gene?
Or am I just really derpy?

It is still entirely possible that there will be a longhaired dog. Option B however suggests that the dogs have lost that gene through constant longhaired dogs being born and therefore the gene being 'weeded out' if you will. Edit: My first guess would have been A as well.
