A person who has one copy of an abnormal gene for a recessive disorder is a carrier for that disorder, even though he or she may show no signs of it.
The first thing you need to realize is that cystic fibrosis (CF) is a genetic disease. Each human being has 23 pairs of chromosomes in each cell of the body.It is a mutation on the seventh pair that causes CF. This gene is very complex, and well over 1,000 different kinds mutations on this gene can manifest as CF.s a genetic disorder, it is passed along from parents to child. In the case of CF, two CF genes must be inherited, one from each parent. This makes CF a recessive disorder, because two genes are needed for the condition to manifest.
