The most common and/or prominent plant species in a site or vegetation type.
The most common or prominent plant in a vegetation type or region.
A gene that expresses itself to the exclusion of the expression of its allele.
Important or powerful.
In genetic inheritance, a gene that produces its effect regardless of the information coded on its paired gene.
Describing a gene (or its corresponding characteristic) whose effect is shown in the individual whether its allele is the same or different If the allele is different it is described as recessive and its effect is masked.
In genetics, concerning a trait or characteristic that is expressed in the offspring although it is carried on only one of the homologous chromosomes.
A phrase employed in genetics to define the traits of a gene. Many traits are dictated by a single pair of genes, with each parent contributing one gene from the pair. The dominant gene in the pair supersedes its corresponding recessive gene, permitting its expression.
For instance, the gene responsible for brown eye color is dominant. Therefore, if a child receives the gene for brown eyes from one parent and the gene for blue eyes from the other, the child will have brown eyes.
Certain genetic disorders are dictated by a dominant abnormal gene that overpowers the impact of a corresponding normal gene, which is recessive. Marfan syndrome and Huntington’s disease are examples of these disorders. In such situations, a child will be affected by the disease if the gene is inherited from one or both parents.
