Study Notes

  • The Human Genome Project's completion at the millennium's turn opened possibilities for understanding humans.

Whole Genome Sequencing

  • Within two decades, whole genome sequencing became accessible to households for approximately $600.
  • Black Friday discounts reduced the price to as low as $199 in some cases.
  • This advancement, along with big data, led to startups focused on decoded life, including rare disease diagnostics, personalized medicine, prenatal genetic consulting, and ancestry composition.

Genetics-Based Dating Platforms

  • Genetics-based dating platforms emerged, promising DNA secrets would facilitate informed partner selection.
  • These platforms focus on: physical attraction based on immunological diversity, psychological compatibility based on hormonal levels, and haplotype compatibility for reduced risk of children with severe rare diseases.

Physical Attraction and Immunological Diversity

  • The theory suggests people prefer partners with immune systems different from their own, particularly in women's partner selection.
  • The major histocompatibility complex (MHC), encoding cell surface proteins for pathogen identification, determines this on a genome level.
  • In humans, MHC classes I and II form the human leukocyte antigen (HLA).
  • MHC diversity arms offspring with more antigens to detect pathogens, increases resilience to infections, and reduces the likelihood of partners being related.

"Sweaty T-Shirt Experiment"

  • In 1995, Claus Wedekind's "sweaty T-shirt experiment" became a hallmark of genetics-based sexual attraction.
  • Women preferred the scents of men whose MHC alleles differed from their own, but only if they weren't using hormonal contraception.
  • A 2001 study correlated MHC with fragrance preference.
  • Women preferred odors different from their paternally inherited MHC alleles, according to a 2002 study.

MHC Dissimilarity

  • MHC dissimilarity in long-term relationships reduced women's attraction to other men and increased fidelity, as shown in a 2006 study.
  • A Dresden research group found that women are more attracted to male partners with dissimilar HLA, which increases their sexual satisfaction and willingness to procreate; this effect was not reciprocated in men.
  • Body odors play a role in women's sexual satisfaction.
  • HLA plays a pheromone-like role, forming the scientific basis for attraction prediction on DNA-based dating platforms.
  • Platforms prioritize HLA dissimilarity, as similarity is thought to result in breakups.

Homosexual Attraction

  • Research is ongoing regarding genetic basis, including a 2019 study that identified 5 relevant loci connected to sex hormone regulation and olfaction.
  • Olfaction plays an important role in human sexual preferences.

DNA Romance

  • DNA Romance matches users based on romantic chemistry measured by differences in 102 MHC region DNA markers, and personality compatibility via the Myers-Briggs Type Indicator.
  • The MHC region may explain up to 40% of attraction.

Instant Chemistry

  • Instant Chemistry offers couples compatibility assessments.
  • It uses HLA genes and MBTI personality tests and calculates neurocompatibility scores using the DRD4, SLC6A4, and OXTR genes.
  • The company classifies customers into 8 personality types and calculates couple compatibility but these algorithms lack public metrics or validation.

DigiD8

  • In December 2019, George Church founded DigiD8, a dating app that screens users for monogenic rare disease SNPs to prevent matches between carriers of recessive disease alleles.
  • This has ethical concerns regarding discrimination against diseased allele carriers.
  • Church compares the app to Dor Yeshorim, a program that reduced the incidence of diseases in Jewish communities through premarital genetic screening.
  • DigiD8 puts matchmaking decision power in Church's hands.
