The condition in which two alleles in a heterozygous organism are both expressed, so the phenotype has characteristics of both of the phenotypes of individuals homozygous for either allele. Blood type (A, B, AB, O) is an example of codominance.
designating genes when both alleles of a pair are fully expressed in the heterozygote odon: the nucleotide triplet in messenger RNA that specifies the amino acid to be inserted in a specific position in the forming polypeptide during translation
in stands with a closed canopy, those trees whose crowns form the general level of the canopy and receive full light from above, but comparatively little from the sides. In young stands, those trees with above average height growth.
a tree whose crown helps to form the general level of the main canopy in even-aged stands or in uneven-aged stands, the main canopy of the tree's immediate neighbors, receiving full light from above and partial light from the sides Cohort: a group of trees developing after a single disturbance, commonly consisting of trees of similar age, although it can include a considerable range of tree ages of seedling or sprout origin and trees that predate the disturbance
() Applied to a dominant tree which falls a little below the general top level of the topmost canopy and is about 5/6th of the average height of the predominant tree. See tree classes. Appendix II. () ( Ecol.). A species that shares dominance more or less equally with others. ( BCFT modif.).
