This part contains information about genetics which is modelled on real-world concepts. This might be advanced for some. This can be skipped without losing any vital information.
Possible Alleles
There are 8 different versions of the alleles that code for Marks or lack there-of.
The non-mutated allele is the one that codes for no Mark. Other than that, there are 7 different mutated alleles which each correlate to the specific Fae Marks.
The 7 mutated possibilities appear as a result of active altering of genes done by Fae and cannot be obtained naturally through mutation seen over many generations.
There are 2 ways to be marked:
- Single-Marked: the marked person only has one allele which codes for a mark. The second one is the allele which codes for no mark.
- Double Marked: the marked person has two alleles which code for a mark. It can either be for the same mark or two different ones. Double-Marked people are rarely born alive.

The table shows the 8 different possible alleles which can
be found in the genome at the spot which will determine
whether a person has a mark or not.
Dominance and Recessiveness
The 7 mutations which code for Marks are all dominant, whereas the allele which codes for no Mark is recessive. The condition is autosomal dominant, which means there is the same chance that a female or a male receives the gene from their parent.
Marked and Unmarked (Any Mark)
The table below shows the outcome of a single-marked person and an unmarked person having children.
The outcome is the same no matter what mark the marked part possesses.
Outcome: 50% chance of single-marked, 50% chance of unmarked.

Marked and Marked (Identical Marks)
The table below shows the outcome of two single-marked people with the same mark. This can result in a double-marked homozygote.
Outcome: 50% chance of single-marked, 25% chance of double-marked homozygote, 25% chance of unmarked.

Marked and Marked (Unidentical Marks)
In this example, the parents are both single-marked but they have different Marks. One has a
Light Mark, the other has a
Fire Mark. This can result in a double-marked
heterozygote.
Outcome: 25% chance of single-marked (Fire), 25% chance of single-marked (Light), 25% chance of double-marked heterozygote, 25% chance of unmarked.

Other combinations
Other possible combinations would be:
- Unmarked and Unmarked
- Double Marked homozygote and Unmarked
- Double Marked homozygote and Single Marked (Identical Marks)
- Double Marked homozygote and Single Marked (Unidentical Marks)
- Double Marked heterozygote and Unmarked
- Double Marked heterozygote and Single Marked (3 mark types)
- Double Marked heterozygote and Single Marked (2 mark types)
- Double Marked heterozygote and Single Marked (Unidentical Marks)
Only the combination of 2 Unmarked would be viable, as 100% of Double Marked individuals are infertile.
2 Unmarked individuals would have a 100% chance of birthing an Unmarked child.
The rest of the combinations would never be possible because Double Marked people cannot reproduce. Not even the ones with two of the same mark.
Double Marks and Incomplete Dominance
If both alleles code for different marks, there will exist what is called incomplete dominance, a mix of the two which blends them together but makes each of them weaker. Individuals with incomplete dominance are unlikely to survive as primal elements aren't meant to coexist within the same organism. Only about 3% of double-marked heterozygotes are born alive. 5% of double marked homozygotes are born alive.
In the odd case that one such person does survive, they will be able to use two types of magic rather easily, but their abilities in each field will be considerably weaker than a person with one mark. A child with two marks rarely lives long if they even make it out of the womb. A person with incomplete dominance will be born sterile.
Nice work! is this the only way to use magic? i really like the idea. It seems so unique. Is the mark visible? how does it manifest? looking forward to more!
Thank you for the comment Dyl :D It is the only way for full humans to use magic yes. The mark depends on the fae who gave it, and it is fully visible. It's placed where the fae touched when giving the mark. If the mark was inherited, it will be placed the same place as where the parent had it. I'll write it in the article whenever I get the time ^-^
Very nice! I like it. and no problem at all!
