question about crosses

This seems like a slow section of the forum! last post was yesterday. lol.

anyways.

i was wondering when crossing two strains which traits generally get passed on from mother and father? traits like type of high, flowering time, yield, smell, taste, trich production etc?

i ask because i'd like to work on breeding my own strains. at first just for my own use but eventually i'd like to pass on my good work to others to grow out and enjoy.



examples of some of the things i hope to accomplish:
1) create fem versions of seeds unavailable in fem form (easy...get a clone...use Colloidal silver = fem seeds)
2) create fem crosses (easy...once again...more colloidal silver)
3) rework some sativas to stay shorter, flower faster but give on a pure sativa effect (this is where my question comes into play) strains like haze, thai, etc. bred with pure indicas (or close to pure indicas) where the indica growing traits dominate but the effect is all the haze or thai or whatnot.

To know what traits are passsed on you have to start crossing stuff and documenting it and figuring out what gets passed on.

There isn't a encyclopedia or collection of info that tells you what traits in each strain are dominant and which are recessive, you have to find that out yourself as the breeder/crosser.

Good luck lol, theres thousands of other people already doing what you want to do, better start reading.

hmmm ...so it looks like what i expected...the prior info i was given is crap. lol

thanks for the help..someone else tried telling me that females passed on the 'high' and males passed on the growing structure and flowering times. lol

In a cross the seeds will average 25% of seeds with mother traits, 25% father traits, and 50% mix of both. You need to grow out seeds and choose which plants have the traits you want and keep breeding those, always selecting for the traits you like.

generally, female and male offspring of f1s will lean slightly toward the phenos of their same sex parents. that's why you generally select the plant you want most expressed in your females as a mother plant. then there's how dominant a trait is to contend with. afghani genes tend to dominate even at 25% as in skunk #1.

the basic theory is your f1 offspring should be relatively uniform roughly in between the two parents. then, if you want to preserve the traits of either the mother or father, you keep back crossing every generation to that parent. if you want to select traits from both, you cross the offspring back to each other and should she a full random mix of phenos to pick and chose from. the offspring with have mixes of each parents traits. the wider your gene pool, the easier it is to select for multiple traits.

the best way to isolate traits is just to select for them. recessive traits take some coaxing. i like either shorts' or TGA's ugnoring the earliest flowering dominant males and selecting later ones with more recessive genes. it's always easy to breed back to dominant traits i guess the theory goes.

if you want to stabilize a strain, you create 2 separate bx lines selecting for the same traits in both a few generations until you have the exact plants you want then re-introduce the lines back to each other. i like that description better than the overly technical ones graphing dominant and recessive traits and making trees from them etc. any breeders eyes and taste buds should tell them what's best.

so this means that say i have the mother/father i want...i breed them...they produce the F1's...i pick the best female and male and cross them with the parents...so the chosen F1 female gets crossed with the Parent male...and the F1 male gets crossed with the parent female? which produces a backcross correct?

if you want to select traits from both, you cross the offspring back to each other and should she a full random mix of phenos to pick and chose from. the offspring with have mixes of each parents traits. the wider your gene pool, the easier it is to select for multiple traits.

simply breeding the parents i want...then taking those f1's...if i breed my best f1 male and best f1 female ill make f2's correct?

the best way to isolate traits is just to select for them. recessive traits take some coaxing. i like either shorts' or TGA's ugnoring the earliest flowering dominant males and selecting later ones with more recessive genes. it's always easy to breed back to dominant traits i guess the theory goes.

can you explain this last paragraph in more detail so i get what u mean?
thanks a bunch once again hazey. u always come through and help me out all over the forum!

lol i tried to +rep you and it says i gotta give someone else some +rep first...just as proof that you really do always help me out.
