How come some cats are way more affectionate than others?

nickname asked:

I heard a funny story about cats on NPR today. It said reddish/orange cats are more affectionate than others. I have two cats and the orange one is WAY more affectionate and friendly than my gray girl one, (the orange one is a boy!)…. How come some cats are more affectionate than others? Are they just born like that? LIke how poeple are born w/ different personalities?
