Why are you not a clone of your parents or your siblings?
In short: Discover how the biological process of meiosis creates the genetic variation that makes every human a unique remix of their parents' DNA. This video explains the phases of cell division and why siblings are never exactly alike.
Meiosis is the specialized process responsible for the production of egg and sperm cells. Unlike standard cell replication, this mechanism ensures that offspring do not inherit identical genetic material from their parents, resulting in the distinct biological individuality observed in humans.
The video breaks down the specific phases of meiosis and explores how these cellular events drive genetic diversity. By examining how DNA is shuffled during the creation of reproductive cells, the content clarifies the fundamental reasons why siblings possess different genetic profiles.
