Asexual reproduction requires only one parent and produces offspring that are genetically identical clones of the parent. It occurs through binary fission in bacteria, fragmentation in flatworms, and plant cuttings. Organisms that reproduce asexually include hydra, sea stars, strawberries, archaebacteria, eubacteria, euglena, and paramecium. Sexual reproduction requires two parents and produces offspring that share genetic characteristics from both parents. It can occur internally through fertilization inside the female or externally through fertilization of eggs laid by the female. Organisms that reproduce sexually include chickens, iguanas, lobsters, sharks, humans, butterflies, sunflowers, and roses.

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

5. Sexual Reproduction
 Requires two parents that each give ½ of the genetic
information to the offspring
 Offspring share the characteristics of each parent

6. Sexual Reproduction
 Happens 2 ways
 Internally (inside)
 The egg is fertilized by sperm inside the female
 Mammals, birds, reptiles, insects, spiders
 Externally (outside)
 The egg is fertilized by sperm outside the female
 The female lays the eggs and then the male fertilizes
them.
 Fish and some amphibians
 Plants and fungi (pollen and spores)

7. Sexual Reproduction
 Plant Kingdom
 Flowers are the reproductive organs of plants.
 Some flowers have both male and female reproductive
organs on the same flower.

Pass DNA
from parent
to offspring
• Produces more
offspring
• Only need one
parent (easier)
• Simpler
• Exact copy of
parent
• NO variation
• Preserves “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)
