Genetics of Sunrunners and Sorcerers

Special thanks to Anna for this list!

Here's the genetics as explained by Melanie in Sunrunner's Fire:

The faradhi gene is recessive; the diarmadhi gene is dominant. Simply put, think of the Sunrunner gene as being like that for blue eyes, and the sorcerer gene as similar to that for dark hair; they have nothing to do with each other genetically, but the combination---used perceptively---can be startling.

ff: full Sunrunner. Almost all are unable to cross water without becoming violently ill. All are vulnearable to death by iron while working.

fx: "halfling gift." Possible seasickness; in particularly strong bloodlines, an itchy feeling around the edges of consciousness when spell are being worked. Cannot be trained as a Sunrunner.

Dxx: full sorcerer. No difficulty crossing water; not as susceptible to iron; vulnerable to mirror spells. Can be trained as a Sunrunner, as can all with the diarmadhi gene; also, all with this gene who wear faradhi rings feel them burn in the presence of a sorcerer's working, but if they themselves are doing the spell, the rings only tremble a little as if in protest.

Dff: full sorcerer and full Sunrunner. Most cannot cross water comfortably.

Dfx: full sorcerer; halfling Sunrunner. Same as above, but vulnerable to mirrors.

xx: no "magical" genes at all. Susceptible under influence of dranath to a powerful mind's suggestions, especially diarmadh'im using a mirror.

Offspring of faradh'im

	ff = fx		ff; fx
	ff = xx		fx
	fx = xx		fx; xx
	fx = fx		ff; fx; xx

Offspring of diarmadh'im

	Dxx = Dff	Dfx
	Dxx = Dfx	Dfx; Dxx
	Dff = Dfx	Dff; Dfx
	Dxx = xx	Dxx
	Dff = xx	Dfx
	Dfx = xx	Dfx; Dxx

Offspring of both

	ff = Dxx	Dfx
	ff = Dff	Dff
	ff = Dfx	Dff; Dfx
	fx = Dxx	Dfx; Dxx
	fx = Dff	Dff; Dfx
	fx = Dfx	Dff; Dfx; Dxx
