Explanation:
Detailed explanation-1: -Scientists estimate that about 80 percent of an individual’s height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
Detailed explanation-2: -Since 2006, genome-wide association studies have found more than 50 genes associated with obesity, most with very small effects. Several of these genes also have variants that are associated with monogenic obesity, a phenomenon that has been observed in many other common conditions.
