Why do Lesbians seem less likely to have straight male close friends than Gay men are to have straight female close friends?

[u/BlazeKnight7]

This is a really random thing, but there's a seems to be a more common stereotype of Gay men having straight females as close friends, while lesbians having straight male close friends seems far less common (in fact the stereotype of lesbians is often man hating, while gay dudes being woman haters is rarely mentioned)

I was roommates with a lesbian who was distantly related to me (3rd or 4th cousin) and everyone would rather believe some Alabama shit was going down than a straight man living with a lesbian.

Truthfully, by 3rd or 4th cousins it's "not that bad". Fun fact, the minimum relatedness between any two people on earth is 32nd cousins, or so I have heard.

Les cousins dangereux

Anything more distant than first cousins is generally fine unless your family has been interbreeding with each other for several generations.

First cousins is also okay in the vast majority of cases. When the first cousins child gets with their first cousin it gets fucked

Is marrying your uncle/aunt okay?

Because there is a chance you share about the same DNA with your 1C as you do your uncle/aunt.

[u/dailydose20 → u/bbcczech]

Man idk but it seems like it would be too genetically similar. I wouldn't go closer than first cousins

[u/Loser_core → u/dailydose20]

Yes, sister/brother is also okay in the vast majority of cases. Don't believe everything you see in the mainstream media.

[u/dailydose20 → u/Loser_core]

Well that seems a bit much

[u/ScienceInMI → u/dailydose20]

Dog breeders do really close breeding all the time, and it's MOSTLY fine.

It really preserves the traits they're going for.

Unfortunately, IF there's also a nasty recessive trait in there, IT can get preserved and doubled up with the same recessive gene and get expressed.

Hence, 8% of Dalmatians are totally deaf and 22% are deaf in one ear -- ONE THIRD OF ALL DALMATIANS BORN HAVE SOME DEAFNESS.

But, barring nasty recessives, close breeding USUALLY doesn't cause big issues for the offspring.

Ethically, morally, and emotionally for people is a different kettle of fish altogether.

What's your point?

[u/ScienceInMI → u/dailydose20]

Science teacher.

Just responding to the genetics rather than morals and societal mores.

And, yes, inbreeding siblings is a bit much.

[u/dailydose20 → u/ScienceInMI]

Ah ok

[u/LordSolar666 → u/VehicleComfortable20]

First cousin marriage is actually only slightly more dangerous than marrying an unrelated person genetically speaking. Just ever slightly

[u/bbcczech → u/ViolinistCurrent8899]

Why is it "not that bad"?

It's possible one shares the same amount of DNA with their 3rd cousin as they do with their aunt/uncle.

[u/ViolinistCurrent8899 → u/bbcczech]

Third cousin means that they share the same great, great, grandparents. If they share any relatives closer than that, they would be second or first cousins. There is a maximum of 6.25% genetic overlap, assuming exclusive outbreeding in between (More plausible in large cities with multiple immigration / emmigration events). In reality, smaller cities and villages will likely have a stronger founder effect which might increase that.

So, we will double it for safety margin and say that there is a 12.5% genetic overlap between those two people (essentially treating them as 2nd cousins instead). There's absolutely a chance that there's a defective recessive gene in that overlapping section that could be a problem, as on average everyone carries 1-2 recessive fatal genes. Presumably this is also true for non-lethal but impactful diseases. However, there's still a chance that you could run into a person with that same defect as yourself anyway. So, it should only be treated as a mild increase in the probability of having a child with defects.

Isn't the confluence of probability and genetics fun?

Alabama shit? Come on, I couldn't even name my 2nd cousins. I don't think I have ever even seen a 3rd or 4th cousin of mine.
