Hypothesis

Do common HLA alleles correlate with better health outcomes?

Conclusion

Women with more common HLA alleles reported better health and fewer illnesses, but this was not reflected in male ratings of their attractiveness or health.

Supporting Evidence

  • Women with common HLA alleles reported fewer cold and flu bouts per year.
  • Women with common HLA alleles rated themselves healthier than those with rare alleles.
  • HLA heterozygosity did not predict health measures in women.

Takeaway

This study found that women with common HLA genes felt healthier and got sick less often, but men didn't think they looked healthier or more attractive.

Methodology

The study involved 59 female participants who completed health questionnaires and had their HLA alleles typed, with male participants rating their attractiveness.

Potential Biases

Potential bias due to the self-reported health measures and the specific population studied.

Limitations

The sample size was small, which may have limited the statistical power of the findings.

Participant Demographics

All participants identified as Tswana, aged 18-26.
