Anecdotally, AMWF sons have been observed by commentators on r/hapas to be more masculine on average than WMAF sons. We outline the cause of this phenomena.
We state with exact certainty that AMWF sons inherit more androgen receptors from their White mother’s X-chromosome and that WMAF sons inherit less androgen receptors from their Asian mother’s X-chromosome.
We state with less certainty, despite the circumstantial evidence in favour, that AMWF sons inherit the conditions for higher prenatal and postnatal testosterone from their Asian father’s Y-chromosome and that WMAF sons inherit the conditions for lower prenatal and postnatal testosterone from their White father’s Y-chromosome; and that both AMWF sons and WMAF sons inherit similar amounts of 5-a reductase.
- Serum Testosterone (ST):
- 5-a Reductase (5a) / Dihydrotestosterone (DHT):
- Androgen Receptors (AR):
- B > W > A 
- Length of CAG Repeat  (LCAGR):
- Prenatal Testosterone (PT):
- Serum Testosterone (ST) and Prenatal Testosterone (PT):
Set I – Verified Scientific Facts (in no order) – Hormones and Receptors
- The testes produce testosterone
- The Y-chromosome promotes the growth of testes in the fetus
- Testosterone ‘works’ by binding and activating with androgen receptors
- Androgen receptors are chiefly located in the chest area
Set II – Verified Scientific Facts (in no order) – Inheritance Patterns
- Sons inherit their Y-chromosome paternally and their X-chromosome maternally
- On average, the sons of Asian men and White women (AMWF) inherit lower LCAGR from their White mothers, and therefore, more ARs
- On average, the sons of White men and Asian women (WMAF) inherit higher LCAGR from their Asian mothers, and therefore, less ARs
Set III – Verified Scientific Facts (in no order) – Inheritances in Europe
- Y-DNA haplogroups delineate patrilineal descent, and therefore, the inheritance of Y chromosomes
- N-haplogroup Europeans such as the Finns are patrilineally descended from ancient East Asian men (65% yDNA) and matrilineally descended from indigenous European women (90% mtDNA) 
- N-haplogroup-majority Europeans such as the Finns exhibit higher PT than non-N-haplogroup-majority neighbours such as the Swedes or Danes, by markers of 2d4d ratio and facial morphology and spatial:verbal intelligence ratios (in line with Asians); and higher DHT by way of markers of testicle size and weight and sperm production 
Set IV – Verified Scientific Facts (in no order) – Inheritances in Polynesia
- Samoans, Tongans, and non-Maori Polynesians are paternally Chinese  and maternally Melanesian. They are the AMBF equivalent of Finns, smarter, stronger, faster, and tougher than pure BMBFs.
- Half of Maori men are paternally European, but the Maori men that are represented in contact sports disproportionately exhibit paternal Chinese ancestry.
Set V – Unverified Cultural/Unofficial Facts (in no order) – Physical Effects of Hormones, Receptors, and their Inheritance Patterns
- AMWF is outnumbered by WMAF in America (3:1)
- There are proportionally (9:1) more AMWF sons than WMAF sons in contact-sports in America; more so (27:1) in ratio-adjusted terms 
- Mental health is poorer in WMAF offspring than in AMWF offspring
- The Finns and Scandinavians live in the same environment and climate, eat the same food, receive the same education, play the same sports – the Finns are a ready-made control group for the study of the influence of a deviate yDNA profile amid the uniform mtDNA and yDNA profiles of the neighboring Scandinavians (and other Northern Europeans)
- Finns have the highest # of Summer Olympic gold medals per capita  – and the highest # of Summer Olympic medals (gold, silver, and bronze) per capita after weighing (4-gold, 2-silver, 1-bronze) . The nearest non-haplogroup-N countries (Hungary and East Germany) benefited from the Soviet doping regimen 
- Male Olympic Gold medalists for countries such as Denmark, Norway, and Sweden disproportionately exhibit facial morphology of N-haplogroup males – for example, Kjetil Andre Aamot, the first entry and the most decorated in the Wikipedia list of ‘Olympic Gold Medalists for Norway’  – (personal note from the admin, he looks like a Jurchen)
Exploring Unverified Hypotheses Based on Hard Scientific Facts
- East Asian facial morphology exhibits markers of comparatively higher PT relative to White facial morphology  – notice the similarities between the Native South African and the East Asian; the African-American is representative of a BMBF-WMBF composite in a roughly 80:20 ratio and exhibits proportionally reduced markers of PT
- East Asian physical morphology exhibits markers of excess testosterone’s aromatization into estrogen – we say excess testosterone b/c the facial morphology is indicative of such
- PT conditions appear to inherited through the Y chromosome – if the Y chromosome triggers the production of testes, why should it not determine the base production of ST within those testes, within the womb, however affected by external factors? There is already evidence in the marked masculinity of Finns relative to other Europeans, and for no apparent reason other than a significant deviation in the frequency of an ancient East Asian Y chromosome (N-haplogroup)? There is even a trend for European countries with a significant I-haplogroup minority (Germany and Scandinavia) to report taller average male height [31 – 32]
Conclusion [(scientifically verified) and (scientifically unverified, but strongly supported by tangential evidence)]
We conclude by restating the Abstract.
- AMWF sons are more masculine than WMAF and WMWF sons
- AMAF sons are more masculine than WMAF sons
- AMAF sons are more masculine than WMWF sons in terms of facial morphology and general mentality – but less in terms of muscular build
- White men are promoted by White mtDNA and penalized by White yDNA
- Asian men are promoted by Asian yDNA and penalized by Asian mtDNA
- AMWF sons get the best of both worlds, Asian yDNA and White mtDNA
- WMAF sons get the worst of both worlds, White yDNA and Asian mtDNA
Interesting Areas of Investigation
- Spatial intelligence being significantly hormonal, and WMAF sons being endowed with less PT in-foetus, it could be that AMWF sons are also more spatially intelligent than WMAF sons – and in the case of Finns, we see that their raw IQs and spatial:verbal intelligence ratios are very East Asian in profile and that their educational attainments are often better than the best of the best Europeans 
- The Finns and other N-haplogroup males, as 500th generation sons of AMWF, are the most athletic, intelligent, and masculine of Europeans; as a people, they seem to be in possession of the best of all worlds – there is much research that can be done here to investigate the most optimal configurations of Asian yDNA and White mtDNA
- How much serum testosterone is needed to offset the lack of androgen receptors in Asians? How much more serum testosterone do Asian men have on average than men of other races? We know for a fact that for Asian men, androgen-related disorders continue to be reported well past the CAG-length cut-off in which men of other races stop reporting them
