Miqo'te Male/Female Relations and Views on Marriage

[Terrini]

I have a Miqo'te Keeper alt character I use for roleplaying, and during a session today, the question was asked of what ARE the Miqo'te views on marriage and Male/Female relations? Is inbreeding common because of the rarity of males? Do they HAVE "marriages" at all?

It's fairly clear about the Seekers that they're the polygamous type, one male heading many females. But the ratios are supposed to be true for Keepers as well and we do not hear much about their society and these kind of relations, so I was wondering if people could help me find the evidence about it, because it's pretty hard to remember and sift through all the little details...
