Meiosis produces daughter cells that are genetically different from each other
Meiosis is a type of cell division that makes sex cells. Each sex cell it produces carries a unique combination of genetic information.
Real World
No two human siblings (excluding identical twins) are genetically identical, despite sharing the same parents — a direct consequence of independent segregation and crossing over shuffling alleles uniquely each time meiosis occurs.
Exam Focus
State both mechanisms (independent segregation and crossing over) when asked why meiosis produces genetic variation — naming only one loses marks.
