No genes appeared to be significantly induced by any single genotype of L. monocytogenes , according to either method of analysis.

Polyphenism is a kind of polymorphism where different forms of an animal are caused a single genotype.

The entire natural extent of this species is just two small clumps, and each clump apparently consists of multiple separate stems of a single genotype.

Colonies of marine invertebrates, each representing a single genotype, expand across the ocean floor by asexual reproduction.

Plasticity: when a single genotype gives rise to a spectrum of phenotypes, the phenotype is said to have 'plasticity'.

This is a type of polymorphism where a single genotype produces two or more phenotypes.

When evolutionary biologists describe competition between species, they generally assume that each species is a single genotype whose descendants are mostly accurate copies.

A group of such genotypes is constantly changing, so discussions of which single genotype is the most fit become meaningless.

Thus, the individual genotypes (or species) may be seen as the units on which selection acts and biologists will often speak of a single genotype's fitness.

A polyphenic trait is a trait for which multiple, discrete phenotypes can arise from a single genotype as a result of differing environmental conditions.
