Glossary Term Conditional Genotype
Definition A genotype that is dependent on the presence of some other factor (often a DNA sequence that expresses a protein functioning in specific recombination events). In MGI, conditional is most commonly used to represent Cre-mediated excision of genomic sequences flanked by loxP sites. In most instances, excision of the endogenous genomic sequence flanked by loxP sites is accompanied by simultaneous insertion of some selectable marker (e.g. neomycin). The excised genotype, which is often associated with a phenotype, is dependent (or conditional) on the presence of the Cre-expressing construct.
