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 wrong
- an insertion mutation - insertion of a sequence of extra nucleotides
- a deletion mutation - deletion of a chain of nucleotides
- a non-sense mutation - results in the creation of a non-sense protein
- a transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.

What is an example of a lethal dominant mutation?
the example of lethal dominant mutation is huntington's disease.
Is achondroplasia caused by a mutation?
Yes, it is caused by an autosomal dominant mutation. One copy of the mutation will cause the condition.
Is it true that a defective allele always recessive and a normal allele always dominant?
No. The gene that causes Huntington's is caused by an autosomal dominant mutation, and one form of inherited Parkinson's is also caused by an autosomal dominant mutation.
Is chromosomal mutation dominant or recessive?
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
What is it called when replication is messed up?
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
What is an example of a lethal dominant mutation?
the example of lethal dominant mutation is huntington's disease.
Is the breast and ovarain cancer mutation dominant or recessive?
dominant
Is this mutation dominant or recessive?
it depends on what mutation you speak of. some are and some are not.
Is the mutation asthma recessive or dominant?
Asthma doesn't have a gene so its neither
Is achondroplasia caused by a mutation?
Yes, it is caused by an autosomal dominant mutation. One copy of the mutation will cause the condition.
Is the deletion mutation dominant or recessive?
recessive
Is huntington's disease a mutation?
No, it is a dominant gene
Is deafness a mutation dominant trait?
yes
Would a mutation be a dominate or a recessive trait?
A mutation can be either recessive or dominant depending on what trait it is.
Is the mutation Dpy-10 dominant or recessive?
recessive
Is it true that a defective allele always recessive and a normal allele always dominant?
No. The gene that causes Huntington's is caused by an autosomal dominant mutation, and one form of inherited Parkinson's is also caused by an autosomal dominant mutation.
What is the difference between genetic a disorder and a genetic mutation?
Mutation is any change in the genetic code of an individual regardless of how the change manifests. A genetic disorder is the result of an unfavorable mutation that results through through heterozygous recessive parents producing a homozygous recessive offspring, a random dominant mutation, or multiple polygenic mutations that compound for a negative effect on an individual as examples.
