ANTH 350 Lecture Notes - Lecture 11: T-Shirt, Beringia, Jerky
Document Summary
People and animal prefer the odors of potential mates who are mhc dissimilar. Advantages: keeps you from mating with close relatives, preserves genetic diversity (polymorphisms)i hla system protects from microbes. T shirt test: women smell sweaty t shirts. Women find ones that have most dissimilar hla most attractive. Same experiment done with women who are using contraceptives: opposite result true. Benefit to hma dissimilar: keeps from mating with people closely related to you. Maybe another reason hla has so many polymorphisms. Increased diversity good for humans; protects against pathogens, better immune response. Also may protect against parasites: hla distribution. Many hlas are unique to certain populations. Hlas can help determine the relationship between populations: takehome exam. Ghost in your genes paper also 1-2 pages, 11 points, one inch margins, 1-2 pages. Midterm- take home, turning it online: hla, siberia and the americas. Population specific alleles among siberian ethnic groups.
