  • 10. Sexual Reproduction - Combine  Individual produced from fusion of sex cells (from 2 parents)  Not genetically identical to parents (half of genetic material from each parent)  Disadvantages:  Specialized organs  Need to attract mate  Inherit ‘weak’ genes  Advantages:  Ability to adapt to changes
