9 Organisms Reproduce to Pass on their Genetic Traits
10 Two Types of Reproduction Sexual ReproductionInvolves 2 parentsEgg fertilized (internally or externally) by sperm to make a ZYGOTEOffspring DIFFERENT from parents
11 Two Types of Reproduction Asexual ReproductionInvolves a single organism or cellCell dividesOffspring IDENTICAL to parentExamples: Budding, Gemmules, Fragmentation, Regeneration, Parthogenisis, Binary Fission, Cloning.
