Table pub.mgd.prb_strain_marker
A record in this table represents a Strain/Marker/Allele association. An associations is qualified using the _Qualifier_key. A Strain can have 0 or more Marker/Allele pairs associated with it.

A Strain may be created as the result of a mutation (transgenic allele), in which case the transgenic allele is associated with the newly bred Strain using this table. For example: MGI:4847055/Tg(Foxi2-EGFP)HX217Gsat, strain of origin: FVB/NTac. New Strain: MGI:5003868/STOCK Tg(Foxi2-EGFP)HX217Gsat/Mmucd associated with MGI:5003868/Tg(Foxi2-EGFP)HX217Gsat via PRB_Strain/PRB_Strain_Marker.
