Crohnâs disease is usually treated with some medications but if complications occur, surgery may be an option to remove the most affected part of the colon or to close a fistula. Ulcerative colitis: Itâs an inflammatory disease that affects the large intestine and rectum only.
If the phenotype associated with a given version of a gene is observed when an individual has only one copy, the allele is said to be autosomal dominant. The phenotype will be observed whether the individual has one copy of the allele (is heterozygous) or has two copies of the allele (is homozygous).f the phenotype associated with a given version of a gene is observed only when an individual has two copies, the allele is said to be autosomal recessive. The phenotype will be observed only when the individual is homozygous for the allele concerned.
Autosomal dominance is a pattern of inheritance characteristic of some genetic diseases. Autosomal means that the gene in question is located on one of the numbered, or non-sex, chromosomes.Dominant means that a single copy of the disease-associated mutation is enough to cause the disease.This is in contrast to a recessive disorder, where two copies of the mutation are needed to cause the disease. Huntington's disease is a common example of an autosomal dominant genetic disorder.Definition from: Talking Glossary of Genetic Terms from the National Human Genome Research Institute.his is in contrast to a recessive disorder, where two copies of the mutation are needed to cause the disease.
