Page "Genotype" Paragraph 3

One's genotype differs subtly from one's genomic sequence.

A sequence is an absolute measure of base composition of an individual, or a representative of a species or group ; a genotype typically implies a measurement of how an individual differs or is specialized within a group of individuals or a species.

So typically, one refers to an individual's genotype with regard to a particular gene of interest and, in polyploid individuals, it refers to what combination of alleles the individual carries ( see homozygous, heterozygous ).

The genetic constitution of an organism is referred to as its genotype, such as the letters Bb.
