As expected, this Y Chromosomal consomic on C57BL/6JEi does not display sex reversal.
This consomic strain bears the Y Chromosome from FVB/NJ on the C57BL/6JEi background and is segregating for agouti, from FVB/NJ, and nonagouti from C57BL/6JEi. It was generated by repeatedly backcrossing an agouti male carrier to a female C57BL/6JEi. In 1996 embryos were generated for cryopreservation by crossing agouti (A/a) males consomic for Chr YFVB/NJ at generation N9 or greater with agouti (A/a) or nonagouti black (a/a) females from the colony also at generation N9 or greater. Thus, some of the cryorecovered pups will be agouti colored and some will be nonagouti black, but all males carry the FVB/NJ Y Chromosome.
Currently there are no related genes or alleles for this strain.
