Researchers from the Skolkovo Institute of Science and Technology (Skoltech) have proposed a new human height inheritance model. Human height is considered a classical quantitative trait that depends on sex, genetics, and the environment. The researchers state that this model will account for the interaction between various factors that influence adult human height. The researchers have published the required data in the European Journal of Human Genetics.
Scientists from different universities such as Novosibirsk State University, the Institute of Cytology and Genetics of the Siberian Branch of RAS, and the Institute of Science and Technology have also analyzed the human height distribution in various populations. The team of scientists from the Skoltech has used an enormous set of data on over 369,000 individuals from the UK and has compared various ethnic groups' heights across the world.
The classical human height model is based on the additivity of various factors. The researchers' team has shown that the interactions between these diverse factors should be considered when studying remote populations or large datasets. The researchers have proposed an alternative height model in which the effect of sex, genes, and the environment are multiplied and not added up. This, in turn, states that height can be regarded as an independent trait.
