Genetic analysis of the maternal factors controlling the survival of trisomy 16 mouse fetuses

AbstractThe B × H recombinant inbred strains of mice were used to undertake a genetic analysis of the maternal factors controlling the survival of trisomy 16 fetuses. The data presented indicate that the prevalence of trisomic fetuses on day 15 of gestation varies significantly with the genetic background of the mother. The strain difference in the frequency of trisomy appears to be the result of selective elimination of trisomic fetuses. Various statistical methods employed to elucidate the genetic architecture of the trait from the recombinant inbred strains data indicate that the number of loci involved in the selection process ranges from one to five. Linkage association with two loci has been found; however, with a low probability level (P= 0.292). © 1993 Wiley‐Liss, Inc.
