Asexual Reproduction Advantages and Disadvantages.

Asexual Reproduction A new organism is produced from one organism and will have hereditary material identical to that of the parent organism.

Asexual Reproduction Pg Introduction  Mitosis is the basis for reproduction by one parent  asexual reproduction  Common in microorganisms,

C ATALYST C OMPLETE IT … SBWAT define asexual reproduction SBWAT define sexual reproduction SBWAT differentiate between asexual and sexual reproduction.

ASEXUAL REPRODUCTION Involves only one parent Offspring are genetically identical to the parent.

Recall: All Living Things Share Certain Characteristics -living things are highly organized -living things obtain and use energy -living things grow and.

Reproduction a process whereby living things produce more living things All living organisms need to do it!!

Asexual vs. Sexual Reproduction Copy words that are red and underlined.

ASEXUAL REPRODUCTION One cell, called the parent cell divides into two daughter cells.

5.2 Asexual Reproduction.  Asexual reproduction requires only ONE parent  Offspring have identical genetic information and therefore are identical to.

Creating Clones. In The House of the Scorpion and The X-Files episode ‘Eve’, the stories focus on human clones that are produced by reproductive cloning.

Asexual Reproduction. ASEXUAL vs. SEXUAL  Requires only one parent organism  Offspring genetically identical to parent (clones)  No specialized cells.

A comparison…. Any form of reproduction in which the offspring are genetically identical to the parent A single parent grows a clone or copy of itself.

Asexual Reproduction Genetics & Heredity

Asexual Reproduction +  Same DNA  Requires one parent  Rapid -  No genetic variation – same DNA  Can outgrow environment

Binary Fission  Simplest form of reproductionreproduction  Parent reproduces genetic material  Divides into two daughter cells  Examples  Bacteria Bacteria  Protozoa  Some Algae

Budding  New organism develops from an outgrowth or bud bud  Examples  Hydra Hydra  Yeast Yeast  Sponges

Spores  Specialized cells with tough outer coating which protects inner cell  Examples  Ferns Ferns  Mushrooms  Fungi - MoldMold

Regeneration  Ability to re-grow lost body parts  Some organisms can grow whole new organism from a single piece of the original  Examples  Sea stars, star fish  Salamander Salamander  Gecko Gecko

Vegetative Propagation  Cells separated from parent to form completely new independent individualindependent individual  Examples  Roots  Stems  Runners  Cuttings Cuttings  Other structures: tubers, corms, bulbs

Cloning  Scientifically engineered, genetically identical copies of a biological entity identical copies  Examples  Naturally occurring - Identical TwinsIdentical Twins  Dolly  Body parts
