yes and yes.. How to keep the genes diverse and workable and low instance of lethal and like genes..
Alaska and villages, where its one large extended family, some are that it.. And it shows in some villages.. Several diseases/conditions have a relation to genes. Heart, Cancers, Diebetis and like, some are genetically inclined.. And how to keep the genes from surviving, or becoming concentrted or expressing.. Hemophilia, passes thru the females, but their XX seems to cancel it out? While the male XY does not? and it expresses it in the males.. yes, how to have a gene pool and not make it too narrow to survive. I believe some part of the immune system is linked to genetic diversity and forms. Last I heard, part of why many in Europe seem immune or resistant to HIV, is due to a mutation of the immune system c.1400, that makes it hard for HIV and several other diseases to enter the body or ... not sure of the details.. O Blood type is said to be common in placew where Small Pox has been, and those who survived was O Blood? Not sure of any other possible examples, but suspect they exist.. How much control of the kids love and marriage partners is controlled? Or like the puritans it was, have sex before marriage but as soon as she becomes pregnant, YOU MARRY, it was set up it seems to make sure that breeders met and had kids and not bred with a non-fertile partner? Or so the story goes? Not sure.. Mike ----- Original Message ----- From: Onno Meyer Sent: 06/11/12 10:25 PM To: The GURPSnet mailing list Subject: Re: [gurps] Space Gypsies and Genes?

I had wondered about minimum crew sizes of multi-generation family ships from a genetic viewpoint, and how social organization can modify that. C.J. Cherryh has matrilineal, strictly exogamous families in her ships, which means the family only has to be large enough to maintain all the necessary skills with some redundancy. A typical ship has 100 people, some larger ones have 1,000 but that is generally seen as an impractical size, cf Merchanter's Luck and Finity's End. These families would match the Haida clans, right? There are several notable effects in Cherryh's univer se: - The culture of the family merchanters is dependent on the stations as meeting places, and on other ships and stations to retain genetic diversity. No single ship could maintain the culture, not even the largest. - No nuclear families, only extended matrilineal clans. The father is from another ship or station, and not married to the mother. (A difference from Haida customs.) The child is raised by the mother and her (male and female) relatives. - Spacers are trained by apprenticeship. Just how formal that becomes depends on the size of the ship. - Economically, the Alliance family merchanters are undercut by Union ships with a more traditional crew. Hard to compete if you haul a nursery around. Compare that to the Travelers in Stargate Atlantis. Here, the ships are survivors of planetary cultures, who had to flee from a powerful enemy. The purpose of their ships is to stay in deep space as an ark for their culture, and they trade only to make that possible, not as a go al by itself. That means: - Cabins will replace payload, even more so than for the family merchanters in A/U. - Every ship must be self-sufficient. - I don't recall their marriage customs. They kidnapped Sheppard to take a gene sample, but that had nothing to do with procreation. Finally, there are ships with family members, like the Enterprise D in Star Trek. Bringing family and children is a perk for the crew, and there are families with a tradition of Star Fleet service, but ships are no clans or families. Some modern freighters develop that way, too. - The ship culture will accomodate existing nuclear family structures, it does not dictate or modify them. - In addition to the 'real' crew, who earn their position with the work they do, there are 'dependents' who may not be qualified to operate a starship. There may help a bit, but offering them scut work as unskilled spacers won't do. More like permanent passengers. - People can retire from the ship to their 'real home' o n shore.
