Does feminizing a seed change it's DNA?

thats is wrong hermies kinda do lol well i dont let them get that far your right lol i should have caught that faster lmao thanks for setting me up btw i would have already felt stupid later. but you expertly already did lmao i got you dont worry kidding

I'm curious for breeding purposes. Is a feminized seed an exact copy/clone of the mother?

In virtually no cases is this true.

The only way this would be true, genetically speaking, is if the mother plant were a perfect homozygote with two identical copies of every gene at every allele.

Otherwise any cross of a hybrid mother plant with self-produced pollen is a normal sexual cross that will be expected to throw off a wide variety of F1 pheno offspring.

However, that said, if you start with a REAL true-breeding mother plant, and self pollenize it, the offspring will be effectively the same as the mother.

If so or if not. Which method is the best to use to create a stable copy of the mother?

*IF* the mother is an inbred line, you can self it (see above).

If (and only if) the mother is an F1 produced from a cross of two different inbred lines, you can recross the parents to recreate that mother.

In *EVERY* other case, the only way to exactly reproduce a mother plant is to clone it.

>>"Does feminizing a seed change its DNA".


This question is sort of imprecise.

You don't really "feminize" seeds, though you can create seeds using two female plants as parents, or even one female plant as BOTH parents.

In either case, you're still doing a normal sexual cross, like a cross between a male and female, and the offspring will contain a mixture of genes assorted randomly from each parent.

The only way the offspring here will be genetically identical to the parents is if

a. Both parents are genetically identical and
b. EACH parent contains two identical copies of EVERY SINGLE GENE in its genome.

Again, the only way this can happen, in practice, is if you cross two parents from a highly inbred line.
