1 The Jackson Laboratory,
Bar Harbor, Maine 04609 Eggs from SJL x SWR F1 mice (SFF1) that had been fertilized in vivo were cultured in vitro in
defined medium. The mean time of first cleavage depended on the strain of male parent. Cleavage
occurred in eggs fertilized by BALB/cWt males 4 h later than in eggs fertilized by SFF1 males. Eggs
fertilized by SJL or SWR males cleaved at different times, but in both cases later than those
fertilized by the F1 hybrids. Measurements on eggs fertilized by males from a pair of stocks consomic for the BALB/cWt or SJL Y chromosomes showed that the genetic determinants of the
significantly earlier cleavage caused by SJL males were autosomal rather than Y-linked, and were
unrelated to those involved in the production of hermaphrodites. No differences were found
between BALB/cBy, C57BL/6By and their recombinant inbred derivative CXBH in their effects on
the timing of first cleavage. Eggs, from SFF1 females, that had completed first cleavage were more likely to form blastocysts when the male was an SSF1 rather than a BALB/cWt mouse.
