How much do the parents' height affect the height of their offspring?

I've heard this a lot from short women - they want tall men so that "our kids will be tall". But is that really how it works? If the father is tall but the mother is short, wouldn't there be an equal chance that their kid would end up with their mom's short genes? And to take it a step further, if you're a tall guy and want tall kids, isn't it better to only go for tall women? And yet I see a lot of tall guys going for short women and insisting that "our kids will still be tall because the tall gene is more dominant". Personally I don't really consider the potential height of our kids when choosing a woman to date. But I'm usually more attracted to taller women because their proportions just look hotter to me, and there's more surface area for me to love lol. But I guess having taller kids would be a plus too if it really works that way.

tldr: What are the chances of the offspring being tall if one of the parents is tall? And how much do the odds improve if both parents are tall?
