Coloration differences

genetic variety... genetic recombination that occurs in meosis... sex gametes reproduce differently than other cells (mitosis vs meosis)

you have your answer right here "im growing nevilles haze outdoors from bag seed labeled as such," Bag seed means you have no idea who "male/female/hermi" or what "strain/genetics" pollinated it, as it came from the bag you bought the weed in. Could it have been the same plant, maybe.... could it have been a different plant and strain that they where also growing.... also maybe. no one knows. The lack of it being an intentional pollination means it is unknown and likely from a hermi or stressed plant end of life. the former usually being the case. Almost always bag seed is bunk and hermi's. There are expectations to this, example chemdog was grown out of a bag seed froma greatful dead concert. and tha lead to the famous OG Kush. My buddy grew out 15 bag seeds from different weed strains he picked up along his travels. Only one plant was a true female, and it was dog shit quality. about 4 where males and rest hermis, they fucked the one female and made more bastard seeds. On top of all this, seeds are siblings. no one brothers and sister are identical "excluding Id-twins" they take aspects from each parent, and with an unknown parent its bound to be different and should be expected. Moral of the story. Don't grow bag seed unless you know the risks and are ok with a very low margin of success. Its much better use of your time to get reg/fem seed from a breeder/bank.

seeds are natures childs, strains got varations- and thats the fun part in my eyes

its genetics: like with your old classmates and brothers & sisters : They all are humans (same kind of plant). But only when you have some from the same Family - they have the same parents - so brothers and sisters of the same parents - but even then they are not 100 % identical. But from the same Family (like your Seed are from the same parents) Even genetic twins (like Seeds) differ a bit in grow and form - while the gens of teh parents are the same. One Sister is 1.60m and one is 1.85m .... When you need 100% identical plants you have go the way with clones, where you cut parts from one plant to grow new plants from it , which then are 100% identical in the genetic Phenotyp of its Clone-Mother-Plant.

A plant's entire genetic blueprint (genome) is largely the same in every cell, but its traits and characteristics (phenotype) arise from a complex process where genes are turned on or off in specific cells at certain times, often in response to the environment. Instead of a fixed outcome, the genetic code serves as a set of instructions that can be influenced by environmental factors, developmental stages, and cellular needs, allowing plants to adapt and express different traits from the same underlying DNA. There will always be a element of "rng" (random number generator), meaning randomness or chance, is a fundamental component of genetics due to random mutations, genetic drift, and the meiosis process that ensures a unique combination of genes in offspring. While natural selection acts non-randomly on these variations, the initial source of genetic diversity is random, shaping the genetic makeup of populations over time.
