A genetic character is described as dominant when its controlling allele eclipses the recessive allele. Dormancy
Inactive as in sleep. Many seeds exhibit dormancy, which is a valuable ecological and evolutionary survival mechanism that ensures survival of the species in the event of some disaster that destroys all non-dormant individuals. Dormancy can be a nuisance in agriculture, and in plant breeding. It can often be broken by mechanical or chemical reduction of the seed coat, or by temperature treatment of the seed.
