““Ruth McQuillan and a massive international team scanned the DNA of 35,000 people across twenty-one European countries, and looked for identical genetic variants on both chromosomes across the whole genomes, thereby identifying consanguinity. The difference between those with first-cousin-like inbreeding and outbred individuals was, on average, three centimeters. Socioeconomic factors played a massive part, and were accounted for in the final analysis. The inbreeding depression on one of the simpler metrics of humans is just over an inch.

Large-scale genetic study shows that close kinship reduces adult height by about three centimeters, highlighting measurable biological effects of inbreeding alongside socioeconomic influences.
In simple terms: Close relatives tend to be slightly shorter due to genetic factors.
