Animal regeneration can produce whole organism or parts of organism and repair injury.

Clones today are done at genetic level by using molecular biology techniques as compared to old days when only nucleus would be removed from the egg cell and desired nucleus is inserted for cloning.

Explanation:

Regeneration is a process in which whole organism or part of which is produced from pre existing cells or group of cells and tissue. Regeneration helps in maintaining the integrity of morphology and physiology.

In lower animals like hydra and planaria whole organism is generated by existing parts. This process is termed as totipotency.

In higher animals however injury repair by mitosis is an example of regeneration.

Plant structure involved in vegetative propagation are: bulbs, rhizomes and tubers.

Vegetative propagation can be done by grafting, cutting, bulb formation, tuber, layering and tissue culture methods.

Cloning is a process in which a genetical or identical copy of an organism or the cell is made by molecular biology techniques. The use of DNA sequences, molecular scissors, stem cells and plasmid are the latest techniques of cloning.

Cloning is used for treating serious diseases as diabetes and heart injury.

In old days one cell would have its nucleus removed and placed into the egg and eventually organism produced

Advantages of tissue culture:

From a single explants, large number of plants can be made.

Obtaining plants of desired trait from tissue culture is easy in short span.

No seeds are required for the growing of new plants.

There are multiple lines of evidence that provide support for common ancestry and evolution. Write 3-4 paragraphs describing at
postnew [5]
<h3>Transitional fossils</h3>

Transitional fossils are any fossilized remains of a life form which show common traits to both an ancestral group and its derived descendant group.

<em> Australopithecus afarensis </em>is a hominid that represents an evolutionary transition between modern bipedal humans and their quadrupedal ape ancestors.

Similarities in DNA

All species in the world share some amount of DNA. Species that are more related to each other share bigger amount of DNA than species that are less related. For example fruit fly and modern humans share 61% of their genome and chimps and humans share 96%.

Evolution of the eye

The PAX6 gene controls where eyes develop in animals ranging from fruit flies, octopuses, to mice and humans.
