🧬 Topic Summary
Genetics is the study of heredity, which is how traits are passed down from parents to offspring. These traits, like eye color or hair type, are determined by genes, which are segments of DNA. Understanding genetics helps us explain why we look similar to our family members and how different characteristics are inherited.
Heredity explains why children often resemble their parents. Each parent contributes half of their genetic material to their offspring. These genes determine the characteristics that are passed down. Sometimes, traits can skip generations, but they are still present in the genetic code.
