Humans have about 20,000 genes, and they influence traits such as eye color, height, and even certain health risks. Genes are arranged on structures called chromosomes. Each person inherits half of their chromosomes from each parent. This is why families often share physical features and sometimes similar health conditions. However, genes are only part of the story. Environment and lifestyle also play major roles in overall health.
