What are the advantages of genetic variation?

Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.

What are the advantages and disadvantages of variation?

Advantages:Due to Variation, organism can be developed to survive in adverse conditions, more resistant to diseases, also it creates diversity. Disadvantages: It can also cause some undesired effects like genetic disorder, diseases, etc.

What are the disadvantages of genetic mutation?

Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.

What is the disadvantage of variation?

The variation can be disadvantageous only when it occurs at individual level. For example, the variation that arises from mutation can be lethal for the organisms. So, organisms which such kind of variation will not survive.

What are some of the disadvantages to this lack of variation?

Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist in the population.

What are disadvantages of variation?

Disadvantages of variation: variation causes lose of linkages of chromosomes, which leads to mutations; most mutations are deleterious. Mutations causes drug resistant by bacteria/fungi/protozoa diseases. It also makes insects /pests to be resistant to insecticides/pesticides.

What are some disadvantages of variation?

What would be a possible disadvantage of a mutation to an organism?

Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

Is there an advantage that we can get from mutation that creates one genetic disease?

For example, the very same mutation that causes sickle-cell anemia in affected individuals (i.e., those people who have inherited two mutant copies of the beta globin gene) can confer a survival advantage to unaffected carriers (i.e., those people who have inherited one mutant copy and one normal copy of the gene, and …

What are the disadvantages of variation class 10?

Those individuals who are not well adapted to their environment are less likely to survive and reproduce. – Disadvantages: Organisms may get a new feature that decreases fitness. Remember that not all variation is good variation and genetic variation is virtually unnoticeable.

Is variation always an advantage?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

How can the genetic variation among species be an advantage or a disadvantage for the individual?

Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

What are the pros and cons of genetic variation?

For a population, it’s almost all upside. Genetic variation is the substrate upon which natural selection acts, meaning that without genetic variation there can be no evolution. It allow species to occupy larger habitat ranges, fulfill more ecological roles, and resist environmental changes.

What are the advantages and disadvantages of genetic engineering?

Potential benefits and risks of genetic engineering There are many benefits to using genetic engineering. It is used in agriculture to do things such as, improve the yields of important economic crops, and provide insect or pest resistance. It is also used in the medical field to create insulin, which can be used for treating diabetes.

What are the advantages and disadvantages of a large variational pool?

The advantage is that the larger the variational pool, the greater the likelihood that at least one of the variations will be better able to adapt to any environmental change— preventing species extinction! The disadvantage is that most such variations will be less able to adapt and so the bearers of those variations will likely die young.

What are the advantages of genetic variation in dogs?

Genetic variation has advantages in that it makes the body more robust. For instance, if there is too little diversity in a gene pool, there is a better chance of getting a “double recessive” disease or deformity. When breeding dogs, genetic variation is called “hybrid vigor,”…
