A genetic relationship refers to the biological connection between individuals based on shared genes. This connection can be observed in families, where parents pass on genetic material to their children, resulting in inherited traits. The degree of genetic relationship can vary, with close relatives like siblings sharing about 50% of their genes, while more distant relatives, such as cousins, share a smaller percentage. Understanding genetic relationships is important in fields like genetics, medicine, and ancestry research. It helps in identifying hereditary conditions, tracing lineage, and studying population genetics. By analyzing DNA, scientists can determine how closely related individuals are and explore their shared ancestry.
