Cross breeding question

Question from a fellow grower:

Let`s say that you want to cross two strains, a haze and a kush for example, or whatever.
Which one should be the male and witch the female? What characteristics gives the male and what the female?

I would have to say that this is a matter of choice. Personal choice. I really do not think it matters actually. If bred correctly and back bred the minimum number of time in order to secure a genetically stable hybrid. You should be happy because, some seeds will show traits of either the Mom, or the Pop.
