What is traditional hybridisation procedure?

Traditional hybridisation procedures used in plant and animal breeding, very often lead to inclusion and multiplication of undesirable genes along with the desired genes.

How does genetic engineering help in overcoming the limitations of traditional hybridization procedures used in plants & animals?

Genetic engineering can overcome all these drawbacks because use of recombinant DNA technology, gene cloning and gene transfer allow us to isolate and introduce only one or a set of desirable genes without introducing undesirable genes into the target organism that too from any distant organism.

What is hybridization in plant?

Definition. Plant hybridization is the process of crossbreeding between genetically dissimilar parents to produce a hybrid. It frequently results in polyploid offspring.

What is the limitation of traditional hybridization procedure?

'One of the limitations of traditional hybridization is that it leads to inclusion and multiplication of undesirable. 'One of the limitations of traditional hybridization is that it leads to inclusion and multiplication of undesirable genes along with the desired genes'.

Where is the use of traditional hybridization procedure?

∗ Traditional hybridisatioin procedures used in plant and animal breeding, very often lead to inclusion and multiplication of undesirable genes along with the desired genes.

What is the advantage of genetic engineering over traditional hybridization?

Genetic engineering can insert genetic material from any life form into any other; conventional breeding generally can only work within a species, or at most, within closely related genera, as when they do wide crosses.

What is insertional inactivation during genetic engineering?

Insertional inactivation is a technique used in recombinant DNA technology. In this procedure, a bacteria carrying recombinant plasmids or a fragment of foreign DNA is made to insert into a restriction site inside a gene to resist antibiotics, hence causing the gene to turn non-functional or in an inactivated state.

What is genetic pollution and why does it matter?

When genetic material is unintentionally introduced to a population, this is called genetic pollution and can negatively affect the fitness of a population (primarily through outbreeding depression), introduce other unwanted phenotypes, or theoretically lead to extinction.

Which of the following is the advantage of genetic engineering?

Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.

What is hybridization in animals?

Hybridization is breeding of two different species [1]. ... These rules consider animals to be different species if they cannot breed together or if they breed together and produce infertile offspring, meaning offspring that cannot have their own babies.

What are the steps of hybridization in plants?

Selection, bagging, crossing, emasculation, distribution.

When did transgenics begin and what plant was created?

The first transgenic plants were reported in 1983. Since then, many recombinant proteins have been expressed in several important agronomic species of plants including tobacco, corn, tomato, potato, banana, alfalfa and canola.

Are plasmids clones of bacterial chromosomes?

Plasmids are separate from the bacterial chromosome and replicate independently of it. They generally carry only a small number of genes, notably some associated with antibiotic resistance. Plasmids may be passed between different bacterial cells.

Which of the following processes and techniques are included under biotechnology?

In vitro fertilisation, synthesis of recombinant gene, correcting a defective gene and developing a DNA vaccine are all parts of biotechnology.

When did Biotechnology begin?

What we think of as modern biotechnology began around the end of the nineteenth century. By then, Mendel's work on genetics was completed and institutes for investigating fermentation along with other microbial processes had been founded by Koch, Pasteur, and Lister.
