mother vs. father pollination

very hard to say because there are all different phenotypes and how dna mixes and how dominant vs recessive genes will appear.

there is really NO WAY to know how they are going to come out unless you are a serious breeder who does it on the daily.

 

if you did that then took all the seeds you get from that and cross breed and breed them together until they all turn out the same or very similar you would have created your very own strain.

now its not as simple as that though because you need to be aware of what traits you're trying make the plants have, otherwise you'll just have horde of randomly inbred plants.

 

Correct... the first breed of X and Y will produce an F1 version of Z.. its usually
pretty stable genetically,but when you breed two Z's together, you get all sorts of
whacky shit, any trait of the mother and father (X and Y) can emerge.

You need to grow a bunch of those F2s to maturity, see what ones do the best and
have the qualities you like, make them seed, and then cross your F2 "Z" seeds with
one of the X and Y original strains to begin to stablize it.. you gotta repeat this
process several times before it becomes a really genetically stable "new" strain.
