Sexual vs. Asexual Reproduction

• Whats the difference???

3
Asexual Reproduction

• Formation of new, individual organism from the
  cell(s) of a single parent

4
Occurs in organisms like plants (taking cuttings,
runners re-rooting)
5
Occurs in single-celled organisms by mitosis
6
Certain animals like sponges, insects, reptiles
and fish can do asexual reproduction
7
Advantages and Disadvantages of Asexual
Reproduction

• PROS
• Dont need to find mate
• Can stay in one place
• Less energy expended
• Can produce a bigger population more quickly

• CONS
• No genetic variation
• Population of clones

8
Sexual Reproduction

• Two individuals produce offspring that have
  genetic characteristics from both parents
• Requires fertilization by specialized sex cells
  made by meiosis

9
Advantages and Disadvantages of Sexual
Reproduction

• PROS
• Genetic variation can lead to new traits, better
  survival and aid evolution

• CONS
• Requires more energy to find mate and process
  usually takes longer
• Slower population growth

Asexual Reproduction
Sexual Reproduction
-Only one parent -Offspring are genetic clones
of parents -No genetic variation! -In some
organisms, it is as simple as MITOSIS
-Requires two different parents -Specialized sex
cells, made by MEIOSIS -Lots of genetic
variation, good for evolution
Method of reproduction
