“Despite a century of research on complex traits in humans, the relative importance and specific nature of the influences of genes and environment on human traits remain controversial. We report a meta-analysis of twin correlations and reported variance components for 17,804 traits from 2,748 publications including 14,558,903 partly dependent twin pairs, virtually all published twin studies of complex traits. Estimates of heritability cluster strongly within functional domains, and across all traits the reported heritability is 49%. For a majority (69%) of traits, the observed twin correlations are consistent with a simple and parsimonious model where twin resemblance is solely due to additive genetic variation. The data are inconsistent with substantial influences from shared environment or non-additive genetic variation. This study provides the most comprehensive analysis of the causes of individual differences in human traits thus far and will guide future gene-mapping efforts.”

The 8th edition of MLA has resulted in changes to the citation format. Correcting the citations on our website will take some time. Until then, please reference the guidelines below to correct the citation format. You will still be using the information provided here, but you may need to adjust the format for MLA 8.

Most MLA citations on our site should follow this format:

Author, A. Title of Source. Publisher, Date, URL. Accessed, 1 Jan 2050.
"Web." removed
  • Medium of publication does not need to be stated if obvious.
  • Listing the "name of the site" is not necessary if it is the same as the name of the publisher.
No brackets around URLs
  • URLs should be placed after the publication date, separated by a comma, and before the date accessed, with a period at the end.

For citing an article in a scholarly journal you will use the journal title instead of publisher, and retain any volume, issue, and page numbers. Use a DOI in place of URL if one is available.
