Some specific charts have become well known by effectively explaining a phenomenon or idea. 1  An Allele chart is a chart originating from the study of genetics to show the interaction of two data points in a grid. 2  A Gantt chart helps in scheduling complex projects.
Specifically, IQ is about 50 percent heritable. (For context, height is 90 percent heritable; weight is 70 percent.) A number like 50 percent heritability does not mean that you get 50 percent of your intelligence from your parents, and 50 percent from the environment.Itâs a more complex, abstract statistical estimate.or body weight, which is about 70 percent heritable, there are 32 genes that have been identified that account for maybe two percent heritability, said Plomin, whose project The Study of Mathematically Precocious Youth is the source of data for Zhao's genetic study. There's a very long way to go..
Lipton reports that the remaining 5 percent is genetic and was caused, you guessed it, by stress somewhere in the ancestry of that person. In other words, what we think of as genetic or a family predisposition to a particular disease or health problem was originally created by a stressful condition or event, somewhere in your family tree.
