摘要: The DDK inbred strain of mouse has a striking particularity: when females are crossed to males other strains they exhibit reduced fertility, whereas the reciprocal crosses (non-DDK x males) fertile (Wakasugi et al. 1967; Wakasugi 1973). low fertility results from an early embryonic lethality, F1 embryos dying near late morula-early blastocyst stage. Genetic analyses 1974) and nuclear cytoplasmic transfers (Renard Babinet 1986; 1990; Mann 1986), have shown that failure develop is due incompatibility between maternally encoded product non-DDK paternal genome. In order elucidate genetic determinism this we analyzed male progeny backcross BALB/c (BALB/c DDK)F1 set recombinant (RI) strains, established progenitors, mated with females. Our indicate single locus, Om, responsible for syndrome located on Chromosome (Chr) 11, very close Sigje locus.
