Sexual vs. Asexual Reproduction What’s the difference???
Asexual Reproduction ď Ž
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
CONS
Don’t need to find mate Can stay in one place Less energy expended Can produce a bigger population more quickly
No genetic variation Population of clones
Sexual Reproduction ď Ž
Two individuals produce offspring that have genetic characteristics from both parents
ď Ž
Requires fertilization by specialized sex cells made by meiosis
Advantages and Disadvantages of Sexual Reproduction
PROS
CONS
Genetic variation can lead to new traits, better survival and aid evolution
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
-Requires two different parents
Method of reproduction
-Specialized sex cells, made by MEIOSIS
-No genetic variation! -Lots of genetic variation, good for evolution -In some organisms, it is as simple as MITOSIS
