Origin and generations of C57BL/6 J. The C57BL/6 J was originated in 1921. Its genome in 1998 was sequenced by the Mouse Genome Project to develop the mouse genome reference sequences. After 14 generations, its genome in 2003 was sequenced to develop Eve6B genome sequences. The DNA used in current study was derived from 2018 C57BL/6 J, 30 generations after its genome was sequenced in 1998. See reference [17] for more details
