Sorceren Genetics and Powers

There are two seperate factors that determine whether or not a person is born with Veins, and the powers that come with them. Such people are known as sorceren, which is both the gender neutral singular and the gender nuetral plural. The feminine form is sorceress in the singular and sorceresses in the pural, and the male form is sorcerer in the singular and sorcerers in the plural. They are fully human and completely cross-fertile with both every other bloodline and non-sorceren humans.   Sorceren are catagorized by blodline. The bloodline is genetically determined and is expressed by the coloration of the Veins and the powers that they grant which are directly causative. Further more, the bloodlines cannot be codominant, which means that each sorceren will express one, and only one, bloodline, though they may have genetic markers for others due to mixed heratige. While there are other features assosiated with the bloodlines, such as skin-tone, eye-color, facial features, etc., they are merely strongly corralative and are inherited seperately. Since there are two seperate factors, it is entirely possible for those without Veins to be carrier of the genetic markers, knowingly or unknowingly.   Each bloodline has a sacred site assosiated with it. The site is called their Homemarker, and anyone that was within a specific radius of the site when it was first imbued with it's power and everyone who was concieved within the radius thereafter had their genome altered in such a way that they had the genetic markers for that particular bloodline. Anyone there at the first imbuing developed Veins, where as those born later may or may not have Veins, depending on other factors.   The first determining factor in determining whether a person is born with Veins is whether a given person has the genetic markers assosiated with any bloodline(s), which can either be inherited from a parent or gained from conception near the Homemarker of the assosiated bloodline. There are eight varieties of the genetic marker for each bloodline, and eight seperate genes that carry them, but overall, the varients do the same thing, so a person needs only to have one of the varients, and since the markers themselves are dominant, only on one allelle, and they have enough of the genetic marker to develop veins. There are also null varients of those eight genes, which most of the non-sorceren population have.   Further more, the number of genes that contain the markers and which of the eight varients they are is functionally irrelevent to the expression of the genes. Which means that a person with a single allelle with the genetic marker and a person with a full set of 16 allelles of the genetic marker would express the power the same way. Which means that it is quite possible and suprisingly common for sorceren to have null genetic markers on some or nearly all of their genes.   Those who have their genome altered by the Homemarker of a particular bloodline will have a full set of 8 genes with 2 copies each of the relevent alleles. Those who inherent the genetic markers from their parents have one allele on each specific gene from each parent, which maybe be any comination of the various bloodline varients or null versions, depending on who their parents were and what they might have inherited from their parents.   Which bloodline will manifest in any given sorceren is determined by these markers. The individual will express whichever bloodline they have the most genetic markers for. The bloodlines are equally dominant with each other, and if two bloodlines have the same amount of markers which is dominant is determined by time of birth. Unless their parents both have very pure genomes, though, there is often an unequal number.   If a person has all null markers, then no matter what else happens, they will be born without Veins, whereas if there are genetic markers for one or more bloodline present, then whether or not they develop Veins at all is a chance based on other factors. If a persons mother is a sorceress, there is a one hundred percent chance that they will be born with Veins. If a child born to a sorceress would have all null allelles, which wouldn't be an impossiblity in certain bloodlines where there was a lot of mixng with the local non-sorceren populations, the child simply would not be conceieved. The first zygote formation would fail. Which can be a source of fertility issues, if the the couple both had non-sorceren ancestors.   If a child's mother is not a sorceress, but the child still has the genetic markers, there are a number of other factors that increase the chances that a child will be born with Veins. If the father of the child is a sorcerer, as opposed to the child just having the genetic markers from non-sorcren parents, then the chance of being born with veins was thrity percent plus fifteen percent higher for each of his parents who were sorceren, and another fifteen percent if the father of the child's mother was a sorcerer(It would be fifteen percent for each of her parents, but if her mother had been a sorceress, then she would have been a sorceress, and her child would have been born with Veins regarless of other factors), with another five percent chance for each of the childs great-grandparents who was a sorceren.   Not only the child's lineage, but the world around them shapes the possibility of them being born with Veins. If they are born on the night of a full moon, they have a twenty percent chance of having Veins, which stacked with their ansectry, though only a ten percent chance on the day before or after the full moon. There iss a ten percent chance of a child being born with Veins if they are born on the new moon, and a five percent chance if they are born on the night before or after. Plus a forty percent chance if they are born during a solar eclipse and a thirty percent chance if they are born during a lunar eclipse, which did stac with the chances confered by the phase of the moon. Along with the phases of the moon, the natural rythem of the seasons. A child born on the solctice has a twenty percent chance of being born with Veins, a child born during the equinox has a ten percent chance of having Veins, and being born on the midpoint gives a child a five percent chance of being born with Veins. All of these stack of course, both with each other, such as when the solcitice falls on the full moon, and with anscetry. If all factors add up to more than 100%, then there is still a one in ten thousand chance of a child being born without viens if their mother didn't have veins.    The times when the the enviromental factors come into play most often is among non-sorceren families is when a ancestor spent time living within an hours walk of a homemarker, or had a torrid affair with a sorcerer that she didn't like to mention. That left one or more sorceren bloodline allelles in their decendents' genetic code, of which the family may or may not be aware, since in high concentration sorceren communities, everyone has veins because their mothers had viens.
