vigor is only an issue when cutting from clones. Vigor "resets" (for lack of a better word) when you start from seed.with an f-2 hybred,can you bread aa to bb and get all f1 ab with f1 vigor?
Sort of, F1 hybrids are naturally more vigorous than F2's...vigor is only an issue when cutting from clones. Vigor "resets" (for lack of a better word) when you start from seed.

The reason an F1 has vigor is because all of the traits are equally present at 50% ratio. The dominant genes are what shows up and recessive genes are hidden. Once you reach the F2 generation all those recessive combinations become possibilities and there will be more phenotypes possible (AA BB AB) The thing is you wouldnt be able to distinguish an AA from Ab because the A being dominant and even if you could, that would be only one set of chromosomes and other pairs could be completely made up of BB genes. Therefore you could never recreat that perfect harmony of AB throughout all chromosome pairs like the F1. The sex of the plant is determined by one set of chromosomes so you could start with an AA male and eventtually get an AA female.Also, if the original aa plant strain is a male and the bb inversely female.when you bread to f-2 will the 1in4 aa&bb be always aa male & bb female? thanks
haha you just gave the non lazymans description ....i was way to fucked up lol.....good one !The reason an F1 has vigor is because all of the traits are equally present at 50% ratio.

No, it's the F1's themselves, not their progeny (F2) that experience hybrid vigor. F1 hybrids are created by crossing two dissimilar stable strains.Havent done much breeding but my understand is that hybrid vigor is only the first cross of two f1's - once you cross the two f1's your first batch of seeds are going to be awesome and vigorous in comparison to the parents - now each cross that follows this becomes less and less stable and you get more and more phenotypes untill you have back crossed 20 generations with the original mother, at that point you would have a perfectly stable hybrid,After f2 you have I think in the neighborhood of 250 phenotypes and this number is not back down to 3-4 distinguishable phenotypes until 20 backcrosses? something like that. Serious breeding is very time consuming and requires a very large number of plants to do well, but theres nothing wrong with doing your own seed runs every now and then crossing new f1 plants with other f1's is a great way to have backup seeds for when your clones just wont root.
If you grow say under 200 plants, your best bet is to take your best plants from seed after you have smoked the bud and done serval grows with it and know its what you want to grow, take a clone off it and put it in a huge pot(10 gallon or more), LST and FIM it constantly and veg it for like 3+ months, then clone the crap out of it, you will be able to take 100's of clones like its nothing.
Pretty much, If you don't have 1,000's of plants and have been breeding for 20+ years your an amateur. That is why I only buy my seeds from people matching this criteria.
