Transcript of Asexual Reproduction

Asexual Reproduction
Asexual reproduction is a mode of reproduction where offspring arise from a single organism and inherit the genes of only that parent.
DNA, also known as Deoxyribonucleic Nucleic Acid is imperitive in asexual reproduction to occur. In asexual reproduction, the offspring is produced by only one organism, therefore there is only one type of DNA to be produced. This is why the offspring of Asexual reproduction is reffered to as a "clone". A clone is copies of DNA fragments.
Why is DNA replication important for asexual reproduction to occur?
(Gap 1) The daughter cell grows on the parent cell
(Gap 2) The daughter cell becomes bigger
(Prophase) Chromatin condenses into chromosomes, the nucleolus disappears
(Prometaphase) Nuclear membrane breaks down,
(Metaphase) Chromosomes line up along the metaphase plate, imaginary plate
(Anaphase) Chromosomes break and form sister cells which push opposite each other
(Telophase and Cytokinesis) Nuclear membranes re-form, nucleoli reappear, chromosomes unwind into chromatin. Myosin and actin contract to cleave cells in two. (basically the sister cells split in two, their independent as well)
How does the steps of Mitosis lead to the relation of two identical daughter cells?
Different types of Asexual Reproductions
Binary Fission is the process where the parent cells divide into two parts, that are known as "equal daughter cells" . A daughter cell is a new cell formed from a parent cell.
Binary Fission
Regeneration is when you have the ability to re-grow lost body parts. Normally earth worms and sponges are responsible for these actions. Animals like these do not have bones, these are often called invertebrates.
Regeneration

Budding is the process when the new individuals (offspring) develop as small growths of buds on the surface of the parent organism. Although this is true, the offspring and parent are not the same size. Organisms such as Sponges, Hydra, and some worts, reproduce by budding.

What is Asexual reproduction?
Mitosis
Mitosis is the process, in the cell cycle, by which a cell duplicates into two genetically alike identical daughter cells. In mitosis, chromosomes (Nucleic acids and protein found in the nucleus of living cells) in the cell nucleus are separated into two identical sets of chromosomes, each in it's own nucleus.
