Sexual vs. Asexual ReproductionWhat’s the difference???
Asexual Reproduction
Formation of new, individual organism from the cell(s) of a single parent
Occurs in organisms like plants (taking cuttings, runners re-rooting)
Occurs in single-celled organisms by mitosis
Certain animals like sponges, insects, reptiles and fish can do asexual reproduction
Advantages and Disadvantages of Asexual Reproduction
PROS
Don’t 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
Sexual Reproduction Two individuals produce offspring that have
genetic characteristics from both parents
Requires fertilization by specialized sex cells made by meiosis
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
Method of
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
