Final answer:
Julio and Antonio are monozygotic twins and have identical genetics. Eye color is determined by genes, which are the same for both twins. However, height and athletic ability can be influenced by a combination of genetic and environmental factors.
Step-by-step explanation:
Based on the information provided, we can conclude that Julio and Antonio are monozygotic (identical) twins. This means that they have identical genetics and inherited copies of the same chromosomes and genes. The fact that they have the same eye color further supports the idea that they have identical genetics. However, it is important to note that genetic factors alone do not determine height and athletic ability. These traits can be influenced by a combination of genetic and environmental factors.
