Human height is one of the biological traits. People have always thought that height is mainly determined by a combination of genetic, diet and environmental factors. However, after humans have recognized the role of genes, they have begun to think that genes play a major role in determining the height. So after the completion of the human genome project, it began to search for genes related to height and obtain its information and knowledge related to health, disease and so on. The most likely next is:. ['The difference in height is in appearance and the difference in health status is also large.', 'Diet, environment, and personal health affect genetics.', 'Finding data related to height genes and empirical analysis.', 'Height-determining genes also affect health, disease, etc.']
