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.

∙ 12y agonot so, theres a mutation i blieve called sickle cell anemia? its positive effect you ask? makes the host immune to malaria.

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.
Are mutations heritable?
If a mutation occurs in a sex cell, then it may be inherited. Any mutation to the somatic cells will not be passed on.
What is the term for any permanent change in a gene of chromosome?
The permanent change in a gene or a chromosome is called Mutation.
Name 2 major types of mutation?
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......
What is dominant negative 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.
Is a mutation deleterious?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
What is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.
Is A somatic mutation is always transmitted to the offspring?
no
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)
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 conditions make G always negative?
G is always negative when H is negative and S is positive.
The Sum of 2 negative integers is always negative?
the sum of two negative integers is ALWAYS negative
Would a positive multiplied by a negative be a positive?
No. A positive times a negative is always negative. A negative times a negative is always a positive.
Is the sum of two negative integers always negative?
Yes, the sum of two negative integers is always negative.
Can an O positive parent have a b negative child?
It is possible (by spontaneous mutation, for example) but unlikely.
When you add two negative integers what will the answer always be?
It will always be negative.
