Genetics — phenotype is any observable characteristic, by any method
“Candidates frequently did not consider that any description of the observable results of gene expression are regarded as descriptions of phenotypes. An observable result is a result that can be observed by any method.”
Sort each item. Anything that is the genetic information itself is genotype; any observable outcome of its expression — even one needing a lab test — is phenotype.
The dividing line: is it the genetic information (genotype) or an observable outcome of expressing it (phenotype)? ‘Observable’ includes anything a test can reveal.
