No, the genotype of a person cannot be determined just by looking at them. Genotype refers to the genetic makeup of an individual, which is not visible. Physical appearance is determined by a combination of genetic and environmental factors.
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%.
Humans without a disorder will have 23 pairs of chromosomes. However, there are many disorders caused by different numbers of chromosomes. For example, Trisomy 21 (Down Syndrome) is a disorder caused by the presence of an extra chromosome 21.
An abnormal condition that a person inherits through the chromosomes or genes is a genetic disorder.
Yes, DNA fingerprinting can show a person's genotype by analyzing specific regions of DNA, which are unique to each individual. It is used to identify genetic variations and patterns in an individual's DNA that can be matched to their genotype.
Both types of neurofibromatosis are an autosomal dominant genetic disorder which means an affected person has a 1 in 2 chance of passing it on in each pregnancy. Neurofibromatosis also can be the result of a mutation in the genetic material of the sperm or egg at conception even if families have no previous history of NF. About half of cases are inherited, and the other half are due to spontaneous genetic mutation
Neurofibromatosis - is a genetic condition... nota communicable disease. You cannot 'catch' it from a sufferer by way of intercourse with an affected person.

how is it possible for a person to have dominant genetic disorder? how is it possible for a person to have dominant genetic disorder?

WOW!! That guy is amazing. A chicken? Histerical, Neurofibromatosis affects only chromosome number 23. It also will affect the brain and is an autosomal dominant genetic disorder.It is when your chromosome has a chicken.

As it is one of the most varied genetic disorders person to person, you can never say. How ever alot of people live a long and healthy life with nf, as i have :)
German pathologist Friedrich Daniel von Recklinghausen is credited with first describing neurofibromatosis type 1 in 1882. NF1 is often called â??von Recklinghausen syndromeâ?? as a result. Scottish JH Wishart is credited with first describing neurofibromatosis type 2 in 1820.
