How is meiosis related to sexual reproduction?
Meiosis allows the offspring produced during sexual reproduction to grow and develop.
Meiosis joins together the sex cells during sexual reproduction to produce new offspring.
Meiosis produces the sex cells that join to form new offspring during sexual reproduction.
