Is it possible for a feminized seed to be of the same parentage as regular seeds?

I will start off with a formal intro, my name is Adam and I'm fairly new to cannabis cultivation. I have a few crops under my belt and I enjoy spending time in my garden. I am about to place another seed order to change up a few strains and see if I can find another keeper or two to add to the collection. I have used both regular and feminized seeds in the past but while browsing through smoke/grow reports trying to decide on what to go with I came up with a theory about feminized seeds that I figure I'll run past some of the more experienced growers/breeders on the site.

My theory is that fem seeds are a different strain (most likely an f2 or backcross) then their regular counterparts.

For my theory to be correct the following statements must be true (it is very possible that they are not true as all my info is gathered from searching and reading old threads, not from asking specific questions)
1. Breeders use reversed females to create feminized seeds (the method used to reverse a female may vary, but the pollination is completed by collecting pollen from a reversed female and introducing it to another female leaving the resulting seeds the genetic blueprint to produce only female and hermaphroditic seeds).
2. Feminized seeds are NOT created by reversing a male plant, collecting the pollen and introducing it to a female plant.
If I am incorrect about either please let me know so i can stop with my silly notions ;)


Next i will start with a brief intro to genetics and filial generation as this knowledge is required to understand what I'm trying to figure out.

If seeds are created by crossing plant A with plant B and those seeds are germinated, grown out, and allowed to pollinate each other the resulting seeds will produce completely different variations than the parents used to create.
I will give an example: Chrystal is not made by crossing a male Chrystal with a female Chrystal, it is made by crossing a specific cut of Northern Lights with a specific cut of White Widow. If Chrystal (referred to as the f1 generation of NL x WW) is bred to Chrystal then this creates an entirely new strain that is referred to as an f2. When two f1's are bred together the resulting f2's are very different then the f1 generation. The reason they are different can be confusing but can also make for a lot of fun when breeding/trying to isolate/pass on different genetics and traits. I will not go into what makes f2's different then f1's as it is not important to know for my theory, but please understand that WW x NL (f1 Chrystal) provides completely different seeds then Chrystal x Chrystal (f2 Chrystal).

Now onto my theory.

If crystal is made by crossing a specific WW to a specific NL (not just any WW or NL will do either, to make the true strain, clones of the original parents must be used) then the exact male and female must be used every time to complete the breeding or the stain changes. If you are creating fem seeds using two females and reversing one then the second female used is not identical to the original male that started the strain and your seeds will not only be fem/hermi, they will also be different because one of the parents used was different than the parents used in the original breeding.

I imagine that most seeds companies that offer both types of seeds start developing a new strain beginning with a regular version and when it is completed to their satisfaction they redo the strain in a feminized form. Unless said company is reversing the original male used to make the regular version and it can not be the same as the regular version as they do not have the identical mother and father.

I will admit I am really baked today and none of this may make any sense but unless the breeders are reversing males and using that to create fem seeds (please let me know if it is possible to reverse a male to create fem seeds) or I'm in the dark about another method of feminizing seeds then how can a batch of regular seeds be the same as fem seeds?

Make sense?

I think I got it. Makes sense to me but then I'm not a breeder.
You are saying that if 2 different f1 females are used to make fem seeds that recessive genes may regroup and create variations that were not seen in the F1s?
Hell....I'm baked too. I'd better read that again!:eyesmoke:

I assume that once a regular strain is created to the breeders satisfaction they then reverse one of the female f1 and cross it to another f1 or back to the original patriarch of the new strain (know as P generation). Neither of these combos give you your original f1 cross though, f1 x f1 is an f2 and f1 x P (original parent/mother) is a backcross (bx/bx1).

You hit the nail right on the head by bringing up recessive genetics, it's funny because I tried including a bit on recessive/co Dom/dominate genes in my op but it got too confusing. If a breeder is selling a femmed f2/bx1 to be the same as the regular f1 then that is wrong, they are totally different strains. F1s and f1xp crosses will create the visual (homozygous) form of their dormant/non visual (heterozygous (sp?)) traits hiding in the f1 generation that were passed on by ONE (not both, if both parents have the heterozygous trait in the P generation (original parents/patriarch generation) then the f1 generation will display this trait in aprox 25% of the seeds.

Sorry, I'm still baked so please bear with me ;)

Oh and if anyone in the know can shed some light on what goes on with femmed seeds behind the scenes pls do, I wonder if this is why a lot of breeders don't do femmed seeds as they feel that this is not the correct way to represent their product, or if this is the reason that companies like greenhouse seeds (and possible others) only sell femmed seeds.

If this is correct how would everybody feel knowing that my pack of NL from X breeder is different then the femmed pack of NL that you picked up from the same breeder (aside from the obvious sexual capabilities that ARE stated in the breeders advertisement).

Seems to me that IF only one plant is used to make fem seeds, (both as donor and recipient) the resulting seeds would likely be identical. But is 2 siblings are used, more variations would be possible. So it would depend on the methods used. Since most strains have a range of phenotypes, I tend to think that the latter method is used.

I bet someone on RIU knows for sure. I am totally guessing. :peace:
