Expression data can provide a guide as to which multiple gene knockouts are likely to yield specific phenotypes.

Mice with a target deletion of the GPR55 gene show no specific phenotype.

Skin colour is a polygenic trait, which means that several different genes are involved in determining a specific phenotype.

This type of saturation mutagenesis within classical experiments was used to define sets of genes that were a bare minimum for the appearance of specific phenotypes.

Functional metagenomic studies are designed to search for specific phenotypes that are associated with molecules with specific characteristics.

Observation parameters can be selected to target a highly specific phenotype.

The specific phenotype varied from mouse to mouse and eye to eye (Figure 2A,B,C).

This concept claims that a tumor is a heterogeneous population of mutant cells, all of which share some mutations but vary in specific phenotype.

The identification and contribution of genetic variation to specific phenotypes can only be performed when other potential contributing factors can be matched across genotype groups.

Recently, specific phenotypes (in maca, 'phenotype' pertains mainly to root color) have been exclusively propagated to ascertain their different nutritional and therapeutic properties.
