To continue:

The Red tribes are no less eugenically obsessed then the civilized Black men of the river valleys but go about it in a different way. they maintain a deliberately low level of technology and political organization and live in a near constant state of war as a means of testing themselves and culling the unsuccessful. Here Rama met, on the battlefield, the genetically superb Warrior Queen Devera who he made his bride (after some loss of blood on both sides). After uniting the Red Tribes Rama and Devera proceeded to conquer the Black empires after which they settled down to have a family. It took all Iset's skill to successfully combine the advanced genome of a Primarch with even so superb a specimen as Devera but in the end she succeeded and the couple had ten children of whom five were daughters.

Rama too came from a sexually egalitarian culture and so it was natural for him to create female gene-seed from the genetic material of his daughters. This same technique was later used by Talyesan to create female gene-seed from his own genetic material.
