Nope Most noticeable ones are negative, like Down's syndrome, Autism and Cystic fibrosis. Some have a neutral effect. Developing an extra finger on each hand, for example, has now real up or downside (except socially, maybe).
Approximately 7% of genetic mutations can be considered beneficial, and these commonly also have a downside. Sickle cell anaemia, for example, reduces the ability to develop scabs over wounds. On the plus side the sickle shape of the blood cells gives an immunity to malaria.

What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
What element has negatively charged protons neutron's and electrons?
None.Protons are always positively charged, electrons are always negatively charged and neutrons are always electrically neutral. And this is true in the case of all elements.
What is the difference between genetic polymorphism and mutation?
A mutation is a genetic change that has occurred in an individual organism. (e.g. an A is changed to a G in a cell of an organism.) A polymorphism is the existence of multiple genetic varieties within a population. (e.g. At a particular place in the genome, some organisms within a population have A's and other organisms within the population have G's.) Note: 1. Mutations and polymorphisms can be advantageous, deleterious, or neutral. 2. All polymorphisms began their existence as mutations. A mutation always occurs in an individual, but can become a polymorphism if it is heritable (i.e. if the mutation affected the germ line) and if it succeeds in spreading through a significant proportion of the population.
A mutation always affects an organism negatively true or false?
No, but most are. From the standpoint of probability it is much easier to break something than to make it better. Especially when the process is completely random.
Which one of the following statements regarding Nucleotides is false?
It is always known as a mutation
What is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.
A mutation in a gene may not affect an individual's phenotype because?
A mutation in a gene may not always affect an individuals phenotype because the mutation may occur in a non-coding region. This is known as silent mutation.
What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Is a mutation always negative?
Mutations do not necessarily have to affect organisms negatively. It is occasionally through the mutation of genes that species are able to evolve and become better adapted to their climate. For example, it has been theorised that one of the mutations of the jaw muscle lead partially to the evolution of humans. Such a mutation had both negative and positive effects: it decreased jaw strength, but allowed the headcase to expand, allowing for the brain to increase in size. So while it could be taken as a negative influence, there have been much greater positive affects to the organism.
Describe the differences between the original and mutated sequences?
An original sequence is a sequence of DNA that has no mutations or damage. A mutated sequence is one that has had some type of damage or change occurs to the DNA. A mutation is not always a bad thing, and may have very little impact on the organism that has the mutation.
What type of mutation is a beneficial to an organism?
Those that increase your health, your survival, your ability to have children and of course too many other benefits to name, here. Generally mutations are the key to natural selection. Beneficial mutations that occur allow an organism to survive longer, thus reproduce more, passing this mutated trait down to their offspring.
Is A somatic mutation is always transmitted to the offspring?
no
Are mutations always bad?
Mutations are not always bad, there are certain cases where a second mutation overcomes the effects caused by the initial mutation. Mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms, or reproduce more quickly. In these cases a mutation will tend to become more common in a population through natural selection. Carriers of the sickle cell allele are resistant to malaria, because the parasites that cause this disease are killed inside sickle-shaped blood cells. So, this suggests that mutations are not always bad, they are also beneficial some times.
Does closing a credit card account which was always paid on time harm your credit score?
Strangely enough, yes it does negatively but temporarily affect ones credit score.
What element has negatively charged protons neutron's and electrons?
None.Protons are always positively charged, electrons are always negatively charged and neutrons are always electrically neutral. And this is true in the case of all elements.
What the attitude in cheerleading?
Cheerleaders represent their school or team with a positive and uplifting attitude! Cheerleaders should be "peppy" but always be aware of their actions in the public eye that may negatively affect them.
Components of an atom are ALWAYS negatively charged?
Electrons
