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?

Edited by Fruit: 7/18/2013 7:36:46 AMIt's not A because they could both have a dominant and recessive gene (Which still gives them short hair because well, it's a dominant trait), which means they have a chance of producing offspring with long hair :P But B makes sense because for them to both have long hair, then they must have only recessive genes :P So because they've only got recessive genes, they can only have offspring with long hair!
