What are genes?
Genes are the hereditable DNA fragments that transmit the information needed to specify traits. This information passes from parents to offspring, generation to generation.
Genes are physically placed and arranged in the chromosomes. Each chromosome contains too many genes that might vary in length.
Genes length depends on the pairs of bases composing them. These sequences vary in number, producing genes of different lengths.
Genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.
According to this information, we can assume that genes are involved in determining the person's Eye color, Number of teeth, and Shape of earlobes.
Athletic ability is also influenced by the environment. Genes might be involved in the physical traits that lead a person to be athletic or not (such as muscles or strength). But the enviroment plays a significant role in determing if the person has the athletic ability or not.
