All is gameplay of our genes. For example: 1.Human height is a typical and important complex trait, which is determined by both actions and interactions of multiple genes. Although an increasing number of genes or genomic regions have been discovered for their independent effects on height variation, no study has been performed to identify genes or loci that interact to control the trait. Height is controlled by both - while a person may have a family history of tallness, if they have a poor diet (especially a shortage of calcium in childhood) compared to their parents, they are very likely going to be shorter. If that person has a more nutritious diet than their short parents, they are very likely to be taller. Once the person becomes an adult, their height changes little.
