Pattern of inheritance in which, when an individual receives contradictory alleles for a trait, only the dominant allele is expressed.
a pattern of inheritance whereby a single gene mutation may lead to a specific genetic disease. Children of an individual affected with a dominantly inherited condition (often referred to as autosomal dominant if the gene is not located on the X or Y chromosomes) have a 50% chance to inherit the gene mutation.
A pattern of inheritance of a characteristic (such as brown eye color) or abnormality in which just one gene or allele is needed to confer the characteristic or abnormality, in contrast to recessive inheritance, which requires two abnormal genes. See also: heterozygous
