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?
Huntington's disease is an example of a lethal dominant mutation. It is a neurodegenerative disorder caused by a dominant mutation in the HTT gene, leading to progressive loss of motor and cognitive functions, eventually resulting in death.
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.
Is chromosomal mutation dominant or recessive?
Chromosomal mutations can be either dominant or recessive, depending on the specific mutation and how it affects the expression of genes on the altered chromosome. Some chromosomal mutations can lead to a dominant phenotype if they result in the duplication or gain of genetic material, while others can lead to a recessive phenotype if they result in the loss or deletion of genetic material.
Is achondroplasia caused by a mutation?
Yes, achondroplasia is primarily caused by a specific mutation in the FGFR3 gene. This mutation leads to abnormal bone growth and results in the characteristic features of achondroplasia, such as short stature and characteristic facial features.
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 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 the deletion mutation dominant or recessive?
A deletion mutation can be dominant or recessive, depending on the specific gene affected and the consequences of the deletion on the protein encoded by that gene. In general, the impact of a deletion mutation on an individual's phenotype will determine whether it is dominant or 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
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.
Is mutation dominate or recessive?

Is the mutation of spina bifida dominant or recessive?
yes it's recessive
