Complement testing of a Thp line revealed a failure of survival of Thp/t0 embryos. The genetic factor responsible for this lethality maps between Brachyury (T) and tufted (tf) on the murine seventeenth chromosome. This lethal factor permits recombination between T and tf and does not affect the transmission of its seventeenth chromosome. Its effect upon embryonic development is similar to that of the t0 haplotype. It would appear to represent a point mutation of a single gene, t-complex lethal zero (tcl0).
