title: [Role of the genetic-physiological interrelationships of mother-progeny in establishing the viability and fertility of mammals. II. The weight of the embryos of BALB, CBA and DBA strain mice developing from transplanted blastocysts].
abstract: The weights of embryos and their placentas obtained by blastocysts of CBA/LacY and DBA/2 mouse strains transfer in recipient females of BALB/c strain and also by blastocysts of BALB/c mouse strain transfer in recipient females of CBA/LacY strain were analysed on the 16th gestation day. It is shown that placental weights are determined by genotypic peculiarities of embryos, although comparative placental weights of different strain embryos could also depend on females fertility. The weight of allogenic embryos (developed from transferred blastocysts) significantly excessed the weight of singenic embryos, and most significant differences were noted in females with small number of embryos. The possibilities to solve some applied and fundamental problems of mammalian reproduction given by the method of interstrain and interbreed early stage embryos transfer are discussed.
