Neurofibromatosis (NF) is a dominant trait. So only one copy of the mutated gene is needed to have the disorder...for example, if someone with NF marries another person without NF, then the chance that their child would have it is 50%.

∙ 12y agoNo. Neurofibromatosis is an autosomal dominant disorder, meaning that only one parent has to have the disorder to pass it on to a child.
This means that if a parent has neurofibromatosis there is a 50-50 chance of passing it on to a child. However, it is important to note that about half the cases of NF are what are known as spontaneous mutations, which means that neither parent has the disorder.
Some cases are so mild however, that sometimes a parent isn't diagnosed until a child is diagnosed with the disorder. NF 1 affects 1 in about 2500 births and NF-2 about 1 in 25,000 births.

Is chromosomal mutation dominant or recessive?
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the 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 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 kind of mutation is triple x syndrome?
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.
Is the deletion mutation dominant or recessive?
recessive
Is the mutation Dpy-10 dominant or recessive?
recessive
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 breast and ovarain cancer mutation dominant or recessive?
dominant
Is the mutation of spina bifida dominant or recessive?
yes it's recessive
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
A gene that is not expressed when paired with a dominant allele is called?
mutation.

Is the lop ear in rabbits recessive or dominant?
Yes, the lop ear gene is recessive since it is a mutation.
Is adrenoleukodystrophy dominant or recessive?
This disease results from a mutation on the x-chromosome. It's recessive considering that a dominant will only cover up things that have occur, for example the damage that has occured, with something else. A recessive will continue to give latent traits. The allele in Adrenoleukodystrophy can only be caused by heredity mutation thus making it recessive.
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
