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%.
No. 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.

Recessive biotch
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
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.
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.
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.
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.

A mutation can be either recessive or dominant depending on what trait it is.
dominant
yes it's recessive
it depends on what mutation you speak of. some are and some are not.
Asthma doesn't have a gene so its neither

Yes, the lop ear gene is recessive since it is a mutation.
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.
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.
