The method of bivariate group heritability was used to estimate the genetic correlation for spelling disability and hyperactivity A similar though not statistically significant value for the genetic correlation was obtained for the two samples (0.29 and 0.42). It was estimated that approximately 75% of the co\u2010occurrence of these two conditions was due to shared generic influences.\n                  <\/jats:p>","DOI":"10.1111\/j.1469-7610.1993.tb01779.x","type":"journal-article","created":{"date-parts":[[2006,12,7]],"date-time":"2006-12-07T19:25:42Z","timestamp":1165519542000},"page":"1137-1152","source":"Crossref","is-referenced-by-count":109,"title":["Hyperactivity and Spelling Disability: Testing for Shared Genetic Aetiology"],"prefix":"10.1111","volume":"34","author":[{"given":"Jim","family":"Stevenson","sequence":"first","affiliation":[]},{"given":"Bruce F.","family":"Pennington","sequence":"additional","affiliation":[]},{"given":"Jeffrey W.","family":"Gilger","sequence":"additional","affiliation":[]},{"given":"John C.","family":"DeFries","sequence":"additional","affiliation":[]},{"given":"Jacquelyn J.","family":"Gillis","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2006,12,7]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004583-198909000-00016"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00919454"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/002221949102400205"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.1991.tb00350.x"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1975.01760290039004"},{"key":"e_1_2_1_7_1","first-page":"107","volume-title":"Biobehavioral measures of dyslexia","author":"DeFries J.
