Genetic study homes in on height’s heritability mystery. Analysis of 20,000 genomes reveals that rare gene variants can help to explain how the trait is inherited. Webunderstanding the genetic factors that contribute to height can shed light on the complexity of personal identity and how it is influenced by biological traits. Webfor height, the first 40 dna markers linked to the trait explained just 5% of its variation. Webthe study authors predicted genetic variants could influence 50 percent of variations in height. Indeed, the 12,111 genes explained differences in height for 40. Webturns out the inheritance of height is a lot more complicated than we thought. Scientists know that nature (genes) and nurture (environment) both play a role, but after. Webby performing a large gwas on adult height, a highly heritable polygenic trait, we have provided answers to several current questions of relevance to the genetic. Webin the largest study of its kind to date, members of the giant consortium — including researchers at the broad institute of mit and harvard, harvard medical. Webthe study, from the international genetic investigation of anthropometric traits (giant) consortium, provides a better glimpse at the biology of height and offers.
