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.
not so, theres a mutation i blieve called sickle cell anemia? its positive effect you ask? makes the host immune to malaria.
False. Mutations are rare in terms of how often they happen compared to size of the genome, however they are not always negative.
No
false
The offspring of the organism will have a mutation.
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.
The permanent change in a gene or a chromosome is called Mutation.
If a mutation occurs in a sex cell, then it may be inherited. Any mutation to the somatic cells will not be passed on.
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......
A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)

G is always negative when H is negative and S is positive.
the sum of two negative integers is ALWAYS negative
No. A positive times a negative is always negative. A negative times a negative is always a positive.
Yes, the sum of two negative integers is always negative.
It is possible (by spontaneous mutation, for example) but unlikely.
It will always be negative.
