Genetics of Heroes
From Activating Evolution
The four gene complex responsible for Hero abilities specifically involves two genes, each of which has two forms, or alleles. To be a Hero, a person must have at least one of each of the dominant alleles. A non-Hero may either have two recessive "a" alleles, or two recessive "b" alleles.
These combinations will make a Hero:
- AABB
- AaBB
- AABb
- AaBb
These combinations will make a non-Hero:
- AAbb
- Aabb
- aaBB
- aaBb
- aabb
Heroes born from two non-Heroes are produced if one parent has two "a" alleles and at least one "B" allele, while the other parent has two "b" alleles and at least one "A" allele. Because of this, they could produce Hero offspring.
AAbb x aaBB, for example, would produce all Hero offspring of the type AaBb.
Aabb x aaBb would produce Hero offspring in the proportion of one in four:
- AaBb = Hero
- Aabb = non-Hero
- aaBb = non-Hero
- aabb = non-Hero
Aabb x aaBB or AAbb x aabB would have a one in two chance of having Hero offspring.
Two Hero parents can even have non-Hero children. These non-Heroes are produced by two Hero parents who have at least one recessive allele of the same gene.
AaBB x AaBB could produce:
- AABB (1/4 chance) = Hero
- AaBB (1/2 chance) = Hero
- aaBB ( 1/4 chance) = non-Hero
AABb x AABb could produce:
- AABB (1/4) = Hero
- AABb (1/2) = Hero
- AAbb (1/4) = non-Hero
However, the cross AABb x AaBB would produce all Hero offspring, since only one recessive allele of each gene could be inherited by any offspring:
- AABB (1/4) = Hero
- AABb (1/4) = Hero
- AaBB (1/4) = Hero
- AaBb (1/4) = Hero
The cross likely to produce the most non-Heroes from two Hero parents is, obviously, AaBb x AaBb, in which the offspring have a seven in sixteen chance of being a non-Hero.
