Genotype Of School Performance – Part 2 of 3
For English, math and science, genetic differences between students explained an regular of 58 percent of the differences in exam scores, the researchers reported. In contrast, shared environments such as schools, neighborhoods and families explained only 29 percent of the differences in exam scores. The left differences in exam scores were explained by environmental factors unique to each student.
Overall, genes had a greater effect on differences in grades in discipline topics such as biology, chemistry, physics (58 percent) than in subjects such as media studies, art and music (42 percent), according to the study published Dec 11, 2013 in the journal PLoS One. None of this means that students are doomed to excel or doomed to fail, based solely on their DNA.
