The good and bad of artificial mutation is square and fast

Enriching the diversity of species. Excellent strains can be obtained to improve the production efficiency of the factory; It can improve the yield and quality of vegetables and grains and alleviate the food crisis.

Summary. Hello! We're glad to answer your questions!

Hello, the pros and cons of artificial variation are advantageous, on the one hand, it can selectively induce the variation of artificial requirements, which is conducive to the breeding of new varieties of plants resistant to Bing and insects. The disadvantage is that it takes a lot of time and manpower and material resources to conduct experiments, and Zui finally selects mutant varieties with stable xing genetics. There are many mutant plants, such as hybrid rice, triploid seedless watermelon, octaploid small hei wheat and so on.

Hello! We're glad to answer your questions! Hello, the advantages and disadvantages of artificial variation are advantageous, and the aspect of jujube cracking can be selectively induced to mutation of artificial requirements, which is conducive to the breeding of new varieties of plants such as Bing resistance and insect resistance.

The disadvantage is that it takes a lot of time and manpower and material resources to conduct experiments, and Zui finally selects mutant varieties with stable xing genetics. There are many different plants, such as hybrid water bench poor closed rice, triploid seedless watermelon, octaploid small hei wheat and so on.

In the rich and colorful realm of the living gods, there is a phenomenon of sensitization and preparation for differentiation of shapes and shapes. Among these mutations, the blind damage is only caused by the influence of environmental factors, and does not cause changes in the genetic material in the organism, so it cannot be inherited, and it is a non-hereditary variation. Some variations are caused by changes in the genetic material in the germ cells, so they can be passed on to offspring, which is a heritable variation.

Biological variation is the main cause of biological diversity.

Hello, the common methods of artificial mutagenesis are:1Physical Law:

Rays (ultraviolet, X-ray, Y-ray, neutron rays), laser microbeams, this ear ion beam, microwave, ultrasonic, thermal, etc. 2.Chemical mutagenesis:

Impregnation, smearing, dripping, injection, application and fumigation. 3.Biological Law:

Spatial conditions deal with mutagenesis, pathogenic microorganisms mutagenesis wild balance, transgenic mutagenesis praise.

Summary. Artificial methods to make biological mutation, is nothing more than the use of chemical substances or physical radiation irradiation, biological variation is often harmful, so the environment changes in nature, organisms will also mutate, after natural selection to adapt to environmental changes of variation is preserved. Artificial methods make biological mutation often cause harm to the organism, and even lead to death, and it is after a large number of tests, a large number of experimental subjects can be selected from the good variants, so the advantage is that the variation of artificial requirements can be selectively induced, which is conducive to the breeding of new varieties such as plant disease resistance and insect resistance, and the disadvantage is that it takes a lot of time and manpower and material resources to carry out experiments and finally select mutant <> with stable inheritance

<> pros and cons of artificial variation.

Hello, I'm glad to answer for you, clear answer: pros and cons of artificial loss mutation: pros:

It increases the probability of biological mutation, makes more biological mutations, and increases the disadvantages of beneficial mutations to human beings: the changes of organisms are not directional, harmful, and the mutations produced are more harmful to human beings.

Artificial methods to make biological mutation, is nothing more than the use of chemical substances or physical radiation irradiation, biological mutation is often harmful, so the environment changes in nature, organisms will also mutate, after natural selection to adapt to environmental changes of the mutation will be preserved or destroyed. Artificial methods make biological mutation often cause harm to stuffy organisms, and even lead to death, and it is after a large number of tests, a large number of experimental subjects can be selected from the variants of a good group tour, so the advantage is that the variation of artificial requirements can be selectively induced, which is conducive to the breeding of new varieties such as plant disease resistance and insect resistance, and the disadvantage is that it takes a lot of time and manpower and material resources to conduct experiments and finally select mutant <> with stable inheritance

We should record the pro, artificial methods to make biological mutations, Tuan Tuan Fan is nothing more than the use of chemical substances or physical rays, biological mutation is often harmful, so the environment changes in nature, organisms will also mutate, after natural selection to adapt to environmental changes of the mutation will be preserved. The advantage is that it can selectively induce the variation of artificial requirements, which is conducive to the breeding of new varieties such as plant disease resistance and insect resistance, but the disadvantage is that it takes a lot of time and manpower and material resources to conduct experiments and finally select mutations with stable inheritance. Most of the mutations are harmful and non-directed, often fatal.

Biological variation is beneficial for an entire population of organisms; But for individual beings, it is harmful.
