Asexual Reproduction Notes
Asexual Reproduction



Reproduction involving only one parent organism
Occurs without meiosis and fertilization
Have the exact same genetic material as the parent
Fission



Cell Division in prokaryotes that forms two genetically identical cells
Simpler than Mitosis because prokaryotes don’t have a nucleus
Occurs in bacteria like E. coli
Mitotic cell division


Asexual reproduction in unicellular eukaryotes when the organism goes through cell division to reproduce
Occurs in Amoeba
Budding


A form of Asexual Reproduction in which a new organism grows by mitosis and cell division on the body of its
parent
Occurs in Hydra
Regeneration


When an offspring grows from a piece of its parent
Occurs in sea stars and planarian
Vegetative reproduction


A form of asexual reproduction in which offspring grow from a part of a parent plant
Occurs in strawberry plants and potatoes
Cloning


Organisms that are genetically engineered by humans from a single cell or cluster of cells taken from a
multicellular organism
The first mammal cloned was a sheep named Dolly
Advantages of Asexual Reproduction



There is no energy or time required to find a mate
The parent can have lots of offspring in a very short amount of time
There is no parental care required
Disadvantages of Asexual Reproduction


Identical to their parents, all members of a species are identical to each other
If a disease or change in environment occurs, all individuals will be affected
