strain question?

in your own words what is the genetic or strain difference between a kush,a haze,and a white strain like white rhino? i understand the difference between indica and sativa but i was wondering why kush is called kush and haze is called haze and what ingrediants do you technically have to have to creat your own new white strain?

kush = stoned
haze = high

I cant put it more simple pretty much haze are a mostly sativa strain that dates back to the 70's
kush is a mostly indica strain that dates to the late 80's early 90's coming from hindu kush mountain range

white strains are strain bread and selected for they large amounts of white hairs when growing more than the average plant
