Sexual vs. Asexual ReproductionWhat’s the difference???

Page 3: Do Now Take papers off side counter Take out the worksheets you finished for homework Homework: None!

Asexual Reproduction

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

Page 4: Do Now Take papers off side counter Take out the worksheets you finished for homework Homework: None!

Occurs in organisms like plants (taking cuttings, runners re-rooting)

Page 5: Do Now Take papers off side counter Take out the worksheets you finished for homework Homework: None!

Occurs in single-celled organisms by mitosis

Page 6: Do Now Take papers off side counter Take out the worksheets you finished for homework Homework: None!

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

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
