5. What are the differences between asexual and sexual reproduction?
Asexual repro uses ONE PARENT while sexual repro uses TWO PARENTS.
Asexual repro uses MITOSIS while sexual repro uses MEIOSIS.
Asexual repro produces offspring that are genetically identical to the parent. Sexual repro produces offspring that are similar but NOT genetically identical to the parents.
Sexual repro involves the FERTILIZATION while asexual repro DOES NOT REQUIRE FERTILIZATION .

6. What are the differences between mitosis and meiosis?
Mitosis produces 2 daughter cells while meiosis produces 4 daughter cells.
Mitosis produces daughter cells with the same # of chromosomes as the parent cell while meiosis produces daughter cells with the half the # of chromosomes as the parent cell.
Mitosis is used for asexual reproduction while meiosis is used for sexual reproduction.
Mitosis is used to replicate somatic cells while meiosis produces gametes (sex cells).
