Dictionary » P » Phenotype PhenotypeDefinition noun, plural: phenotypes (1) The physical appearance or biochemical characteristic of an organism as a result of the interaction of its genotype and the environment. (2) The expression of a particular trait, for example, skin color, height, behavior, etc., according to the individual’s genetic makeup and environment.
Phenotypes result from the expression of the genes of an organisms as well as the influence of environmental factors and random variation. The interaction between these factors have often been represented by the following relationship: genotype + environment + random variation → phenotype.
Related forms: phenotypic (adjective), phenotypically (adverb).

Results from our forumRe: I really need help with the Punnett square & genotypicif there are 25% be Red, 50% Pink and 25% White, it means the red is incomplete dominant. when heterozygous, it wont be appeared as dominant phenotype, it will appear as pink colour. In ur question, [(heterozygous) for red flower] this mean it is not incomplete dominant.

Re: Genetics problems... d. the same as above and above above, just combined 2. Pure breeding means they are homozygous (thus all progeny of self-breeding has the same phenotype, that's not possible for heterozygotes). Since F1 is tall red, the tall and red alleles should be dominant. Now you have to determine the ...

Genetics problems... size being completely dominant to dwarf size. Given a plant was heterozygous for pod shape and homozygous recessive for plant size: a. What is the phenotype of this plant? b. If this plant was crossed to a dihybrid (heterozygote), what would be the phenotypic ratio of pod shape among the progeny? ...

Re: Muscular dystrophy inheritance question... the female may be a carrier with a DMD allele and a wild-type allele for dystrophin, but the pedigree makes it look like she is expressing the DMD phenotype. That confuses me; normally if a female has a DMD allele and a wild-type allele for her dystrophin gene, she is a nonsymptomatic (or mostly ...
