The reason why you may share physical similarities with your parents is due to genetics, not cloning or time travel. When you are conceived, you inherit genetic material from both your biological mother and father. These genetic traits determine many aspects of your physical appearance, such as eye color, hair color, facial features, and more.
Genes are like biological instructions that code for specific traits, and they are passed down from one generation to another through reproduction. You inherit half of your genetic material from your mother (through her egg) and half from your father (through his sperm). Therefore, it's common for children to resemble their parents because they share a significant portion of their genetic makeup.
While the resemblance between parents and children is often noticeable, it's essential to remember that you are a unique individual with your own combination of genetic traits, even if you share some physical similarities with your parents.
Cloning, on the other hand, is a scientific process where an organism's genetic material is copied to create a genetically identical clone. Human cloning is not a natural process and has not been successfully done to create a complete human being.
As for time travel,, time travel remains a theoretical concept, and there is no scientific evidence to suggest that time travel has been achieved. It is a popular theme in science fiction but has not been realized in practice.
In conclusion, your physical resemblance to your parents is a result of genetic inheritance, not cloning or time travel. It's a natural process that occurs during reproduction and is responsible for the shared traits among family members.
