If you take a single copy x-factor mare, and breed her to a small hearted stallion and the resulting filly is small hearted, how many large hearted foals do you think she would produce if only bred to small hearted stallions? ?


That is one type of inheritance that can go either way. That was Sarcasta's point - many different genes act in different ways.

By the way, do you have copies of both of the X-Factor books?
