- a single dominant gene
Examples

When your dominant genes are from your minority parent, it is often assumed that you're only that minority; Caucasian genes just don't stand a chance most times.

Far more likely, it seems, that in a population of 10,000 hominids, one individual was born with the mutation (assuming it was such) and, like a dominant gene, it spread through the population in subsequent generations.

Look... that doesn't matter, and their dominant genes might not matter anymore, either.
-
This suggests that the anomaly is also inherited via the X chromosome, but through a semi-dominant gene.

So if we had more dominant genes than the Neanderthals, we simply outbred them since more Cro-Magnons would be born after each interbreeding episode.

The results showed that different genotypes and cross combinations have dominant genes for different traits. That would be used to bridge the gap prevailing in pulse breeding against abiotic stress.

The resistance in PI 175111 was suggested to be controlled by a single dominant gene, which was later assigned the Ar gene symbol by Robinson et al. (1976).

The genotypes MN-92 and MN-51 were closest to the point of origin, thereby containing the highest number of dominant genes, while MN-98 contained a similar proportion of dominant and recessive genes.

A dominant gene can mask the effect of a recessive gene in an individual's phenotype.
-
If a trait is controlled by a dominant gene, it will be expressed even if only one copy is present.

Morphology
The meaning is directly compositional: 'dominant' (stronger/overriding) + 'gene' (hereditary unit) yields a gene that overrides or determines a trait. This basic sense is cross-linguistically common and a B1 learner who knows the constituent words can infer the core meaning, though detailed genetic mechanics (e.g., masking a recessive allele when present in one copy) are specialist knowledge.
Etymology
Dominant gene can be remembered with a simple picture: imagine two people telling a story but one shouts while the other whispers. The dominant gene 'speaks' louder than the other gene, so its trait 'shows' in the child and the quieter gene is 'hidden' even if that other copy is present.
