When you cross the two plants or strains, ex: NL x Passion all of their traits will be passed on in the seeds that they produce. (Actually I'm not 100% sure if recessive traits are passed on or just dominant traits,) but there is a very, very large possibility of combinations of genes, or traits, that will come out of the seeds produed by the two plants that were crossed. That being said, when you cross NL and Passion purple, let's say you get 35 seeds. All of those seeds will have different traits in them. Some will be big, some will be small, some will be resinous, some not, and some will be purple and some will be green. Just depends but u gotta grow em all out to see which ones are the keepers. I would also suggest maybe crossing your best male and female purple passion plants if your just really goin for purple. Chances are youll get a dank purple outta that. Good luck. And I'm not sure if female plants pass their traits on better than males I would assume not dont quote me though.
