[Characterization of a novel wild-type t(wMPI) haplotype of the house mouse (Mus domesticus L.) from Peru].

Data on molecular genetic analysis of the novel wild-type twMP1 haplotype found in a population of Mus domesticus from Peru are presented. Complementation attribution of the novel haplotype as well as fertility of heterozygotes and transmission ratio distortion (TRD) of the t-carrying chromosome in the progeny of the heterozygous males were studied. Molecular analysis was carried out by means of blot hybridization with the four t-specific probes (Tu48, Tu66, Tu119, and Tu122). Comparison of the results obtained with the data on the structure and properties of the t complexes permitted conclusion on the complete lethality of the haplotype described.
