[li]Assuming an actual breeding program, 1/6 of the children are going to be Teela’s[/li][li]The survival of her bloodline is going to depend on the survival of the group for at least a few generations (although I don’t know if the luck works that way)[/li][li]Back to the first point, I guess (depending on menopause), Teela may also have kids with male offsping of other pairs. And similarly in the second generation (which would have more opportunities for multi-generation crosses (gen 3 could easily breed with gens 2 and 4 (and gen 1 men)), so I’d expect the luck gene to spread into most of the population pretty quickly.[/li][li]Too bad none of the other lucky people were named - Teela wasn’t all that lucky; IIRC, she Protectored before breeding(?) - there was a strong implication that she ended up saving that world for the other lucky people’s bloodlines.[/li][/ul]
