Document Summary
The other 98% was considered genetic junk, because scientists believed these parts were functionless but researchers are now discovering that this is not junk. Parts of these chunks of dna have an impact on humans, potentially affecting everything from a person"s physical size to personality. (many parts with names such as pseudogenes, and riboswitches) Human genome project: research dedicated to the sequencing of human genome: june, 2000, scientists announced they had completed the first draft of the complete human genome. What is heritability: heritability: a statistic that refers to the proportion of observed variance in a group of individuals that can be accounted for by genetic variance. Shirley"s height is 90% heritable: another misconception is that it is constant. Heritability is a statistic that applies only to a population at one point in time and in a particular array of environments. If the environment change, then heritability can change: another, is that heritability is an absolutely precise statistic.
