Hope you poured a drink you could prop a spoon in.
I found stuff by accident again.
Neanderthal women couldn’t conceive with humans.
It would be interesting to see if there are fertility problems between races…
Google autocompletes “are mixed race less fertile”
Rumours that Asians and Africans have more trouble with IVF, even among those who already need IVF.
Infertility information isn’t gathered, which sounds weird for a data-mining project???
They collect the differing types of data but somehow can’t put them together? I call BS.
Cavalli-Sforza’s genetic distances.
I knew HBD would have the answer.
“It is almost the equivalent to having twice the number of children… Thus assortative mating by ethnicity can have large fitness benefits, the largest derived from choosing mates within geographic races.”
they pass on more of themselves, less genetic death per carrier (child)
May increase the values for Ks in parental investment theory.
“In other words and general terms, a white mother will be almost as twice as closely related to a child with a white father versus a child with a black father.”
Bear in mind, this isn’t opinion. It’s genetic.
“But when I turn to the mirror in my bedroom to admire us together, I am shocked. She seems so alien.”
The non-white always benefits far in excess due to dominating the white phenotypes.
They’re hoping to reduce their mutation load/disease risk. The white party loses.
“But still, I can’t shake off the feeling of unease. I didn’t realise how much her looking different would matter… When she was born, pale but with lots of dark hair, I asked the midwife if her eyes would stay blue. ‘Asian genes are very strong,’ she said in what I took to be an ominous tone. No more Brady Bunch kids for me. The midwife has been proved right and every day my baby’s eyes get a little darker.””
Wow so Nazi to insist your daughter look like you. /s
WTF do these r-types expect?
“Since parents share fewer genes with mixed-race children, people involved in interracial marriages are short-changing their own genes, which might explain why people engaged in mixed-race relationships often tend to have lower mate value.”
they signal how they can’t get one of their own so they settled
we all know how attractive desperation is, socially and sexually
“In general, mixed-race people have more health problems.”
The hybrid vigour thing was always a lie, it’s reduced fitness.
According to the field of medicine.
“In other words, an argument could be made that mixed-race families are maladaptive — both for the parents and the children — and undermine one’s genetic interests. As noted by various commenters, multiracial families often do not possess the harmony, cooperation and purposefulness of same-race families, because mixed-race families lack the focus of genetic investment and returns that same-race families possess.”
Like a kind of …selection…
White British genes best at IVF *hums national anthem*
“The study also found that some groups of women including South Asian Bangladeshi, Black African, Middle Eastern, have a significantly lower number of eggs collected than White British women.”
“Furthermore, the increased prevalence of polycystic ovary syndrome (PCOS) in south Asian women may have an impact on egg quality and lower implantation rates.”
“The data suggests that ethnicity is a major independent factor determining the chances of IVF or ICSI treatment success.”
No shit Sherlock. Could it be something of a biological thing going on here…?
“While the reason for this association is difficult to explain, the potential factors could be the observed differences in cause of infertility, ovarian response, fertilisation rates and implantation rates, which are all independent predictors of IVF success.”
“”Infertility affects 10-15% of the population and more people are seeking fertility treatment.”
Isn’t that approaching the rate of mixed race couples? Coincidence, I’m sure. I’d like to check but nobody gives enough of a damn about them to collect the data.
“The reasons behind the variation need to be looked at in more detail but in the future could potentially help improve success rates amongst all groups of women.””
Not if it’s genetic.
“live birth rates of ethnic women were significantly lower”
White women healthiest post-birth
almost like an evolved advantage…
Disgust toward mixed-race couples at biological level
“”That indicates that viewing images of interracial couples evokes disgust at a neural level,” Skinner said.”
“Participants were quicker to associate interracial couples with non-human animals and same-race couples with humans.”
do you ‘fucking love science’ now?
Mixed race babies weaker babies
“contribute to the substantially higher demonstrated risk for stillbirth”
it’s healthy! they tell you
only because they aren’t collecting the data to argue otherwise
I would sue because that’s academic neglect and actual systemic racism.
You really have to search even for data on successful births, then there’s NO fitness advantage by rate.
“This paper investigates whether mixed race couples have different or same fertility level than same race couples”
“Same race couples have on average 1.93 children while mixed couples have 2.05 children. Same race couples have lower fertility because the majority of those couples are white. This data shows that homo and heterogamous unions do not have the same fertility level”
“Mixed race couples have fertility levels that fall in between same race couples; not as high as black or brown couples but not as low as the white couple.”
Regression to the mean, my old friend.
Ya gotta really LOOK.
Oh look, mutation load.
“I can’t find any studies on this at all.”
Red flag to ANYONE else?
“I heard from student of medicine that interracial couples could have problem conceiving child because of their racial differences.”
Why not study it?
They’re screwing over the mixed-race kids.
Possibly killing them, in the long run. That’s just sick, not to study it. Parents deserve to know.
The manosphere dudes with Yellow Fever won’t be pleased.
“In both of these cases there isn’t something mystical going on; God is not smiting those who are sinning by crossing racial lines. Human spontaneous abortion rates are high. Much of this might be due to mother-child immune system responses. It shouldn’t surprise anyone that people from very genetically distinct populations have very different immune profiles. …”
It does if they grow up hearing everyone is biologically equal.
“There is some data which might suggest that genetic relatedness increases reproductive fitness, possibly because of reduced risk of immune incompatibilities between mother and fetus when the father is more closely related to the mother. It stands to reason then that as the father becomes more genetically distant the likelihood of incompatibilities might increase. All of this means that genes matter, and they matter in ways we can possibly predict.”
Do the science.
Irony, the name.
K-selected cooperation in a formula.
Inbreeding is generally better than outbreeding due to inclusive fitness.
applies to other species too
As long as you don’t screw close relations and over many generations, you’re fine.
Wasps! That’s the depth of the barrel I scrape for data on this. Nothing to hide, nothing to fear!
Because for some reason nobody takes the data in humans.
Some strange, open-minded reason.
They find cooperation. In insects.
Needs more genetics, more studies. Generally correct.
