Genetic matchmaking is the idea of matching couples for romantic relationships based on their biological compatibility. The initial idea was conceptualized by Claus Wedekind through his "sweaty t-shirt" experiment. [ 1 ]
[10] [11] In the context of shidduchim, this genetic compatibility check is commonly run within the first three dates or even before the first date, to avoid disappointments and heartbreak. In the United States, testing costs range from $225 to $500. [10] One-half of the actual testing costs is subsidized by private donors and governments. [11]
These are direct phenotypic benefits, sensory bias, the Fisherian runaway hypothesis, indicator traits and genetic compatibility. In the majority of systems where mate choice exists, one sex tends to be competitive with their same-sex members [ 4 ] and the other sex is choosy (meaning they are selective when it comes to picking individuals to ...

Genetic incompatibility describes the process by which mating yields offspring that are nonviable, prone to disease, or genetically defective in some way. In nature, animals can ill afford to devote costly resources for little or no reward, ergo, mating strategies have evolved to allow females to choose or otherwise determine mates which are more likely to result in viable offspring.
Offspring with high genetic diversity seemed to happen only when the operational sex ratio was female-biased, when females were more likely to be able to exert mate choice, and males were less likely to harass females. These results suggest that sexual conflict may interfere with female mate choice for 'good' MHC genes. [37]
