3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.

<h3>How is lineage improvement done?</h3>

The answer is to obtain populations with genetic variability. This can be achieved through hybridization or crossbreeding. Hybridization is the fusion of genetically different gametes, which results in hybrid individuals heterozygous for one or more loci.

With this information, we can conclude that 3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.

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.
