The ridge will appear only if there is at least one dominant allele in both groups.

One copy of the dominant allele is enough to cause the disorder.

The condition is caused by a dominant allele, or variation, of a single gene.

Under normal circumstances it is only possible to eliminate a dominant allele from the gene pool.

Genetic analysis has shown that luminescence is controlled by a single dominant allele.

The dominant alleles are peucedanoid and dominate in the ephialtoid form.

That is, both loci must have at least one dominant allele to produce the phenotype.

The champagne gene is a simple dominant allele responsible for a number of rare horse coat colors.

Other disorders, such as Huntington disease, occur when an individual inherits only one dominant allele.

Unfortunately, two instances (homozygous) of this dominant allele are lethal.

K is another dominant allele of the allelic series which controls feather growth rate.

They suspected that that the ear mutation was from a dominant allele.

One comes from a dominant allele, while the other comes from a recessive.

The cream gene (C) is an incomplete dominant allele with a distinct dosage effect.

It is caused by a dominant allele.

Here, even the dominant alleles result in reduced fitness if present homozygously (see also hybrid vigour).

In genetics, codominance is a phenomenon in which a single gene has more than one dominant allele.

This could happen in the case of loss of genetic material from one homolog bearing the dominant allele.

The dominant allele (I) produces tipped hairs that are fully colored only at the tip and have a white base.

Black is the dominant allele.

FOP is caused by an autosomal dominant allele on chromosome 2q23-24.

The functional, dominant allele of the extension gene (labeled "E") enables the horse to produce black pigment in the hair.

A 24-base pair deletion causes the incompletely dominant allele for melanism in the jaguarundi.

Gray is controlled by a single dominant allele of a gene that regulates specific kinds of stem cells.

Udny Yule (1902) argued against Mendelism because he thought that dominant alleles would increase in the population.
