Dominant Meaning Genetics. Different versions of a gene are called alleles. Means that a single copy of the disease-associated mutation is enough to cause the disease.
Autosomal Dominant from www.genome.gov
A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. Genetics either of a pair or series of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character adjective of genes producing. Dominant genetic disorders are diseases that need only one defective gene copy to be passed down from parent to child.
Dominant negative A mutation whose gene product adversely affects the normal wild-type gene product within the same cell.
Oct 23 2018 Dominant genes are the genes that always express the dominant trait. Alleles can be considered dominant or recessive with dominant being the trait that is observed or shown and recessive being the trait is not seen. Normally two recessive alleles need to be inherited one from each parent for the recessive trait to be expressed but recessive merely means that the trait is only expressed in the absence of the dominant alleles. In genetic terms a dominant trait is one that is phenotypically expressed in heterozygotes.
