Asexual Reproduction

Reproductive Adaptations

From Chapter 2, Lesson 12 of the Coach Biology book ​

• Formation of offspring from a single parent

• Offspring are genetically identical to the parent (same genes).​

​

​Asexual Reproduction

Multiple Choice

Which of these statements describes an advantage of asexual reproduction over sexual reproduction?

• Asexual reproduction requires the presence of other members of the species.

• Asexual reproduction is best suited for rapidly changing environments.

• Asexual reproduction increases the variety of traits in an organism's offspring.

• Asexual reproduction takes less time and usually produces more offspring.

​Examples of asexual reproduction

• Mitosis

• Binary fission

• Budding

• Fragmentation

• Vegetative Propogation

• Cloning​

​Mitosis

Used by multicellular, eukaryotic organisms for growth.

​

Mode of reproduction for many protists​

​

•Done by prokaryotes (archaea and bacteria) and some protists

•One cell splits into two​

• ​Not as fancy as mitosis

​Binary Fission

•Formation of offspring from piece of body that breaks off from the parent organism.

•Some animals like starfish, sponges, planarians, and other worms can do it

•When this happens in plants, it’s called vegetative propagation – an entirely new plant grows from a leaf or piece of stem or root

​

​Fragmentation

•DNA from one organism is inserted into the empty nucleus of an egg

•The egg then undergoes several rounds of division to become a bundle of genetically identical cells

•Cell bundle is surgically inserted into a surrogate mother

•Surrogate gives birth as normal

​

​Cloning

•Cells that are genetically identical to the parent’s cells form a “bud” on the body of the parent

•Bud grows through cell division

•When it is large enough, it breaks off the parent body and lives on its own as a separate organism

•Done by hydras, yeast, fungi, etc.
