Slide2Asexual Reproduction
Requires only one parentOffspring have 100% the same chromosomes as the parent.In other words, the offspring are exact “clones” of the parent.

Slide5Sexual Reproduction
Requires two parents that each give ½ of the genetic information to the offspringOffspring share the characteristics of each parent

Slide6Sexual Reproduction
Happens 2 waysInternally (inside)The egg is fertilized by sperm inside the femaleMammals, birds, reptiles, insects, spidersExternally (outside)The egg is fertilized by sperm outside the femaleThe female lays the eggs and then the male fertilizes them.Fish and some amphibiansPlants and fungi (pollen and spores)

Asexual Reproduction
Sexual Reproduction
Both
Types of reproduction in living organisms
Pass DNA from parent to offspring
Produces more offspringOnly need one parent (easier)SimplerExact copy of parentNO variationPreserves “genetic continuity”
Slower
Need to find a mate
More complex
Mix of parents
Allows for high amounts of
variations
Better at adapting to environment
Mutations! (bad ones)
