[Genetic analysis of the rate of sexual maturation in female mice]. 1976

L Shiuler, and P M Borodin

In studies of the female progeny of complete diallel crossing of BALB/c, C3H/He, C57BL/6, AKR/J mice a considerable influence of the genotype on the variability for such characters as the age of the vagina opening and the weight at that time, the age of the first oestrus and the weight at that time, the weight at 6 weeks was observed. The analysis of the effects of the general and specific combining ability demonstrated that non-additive gene effects play the major role in the determination of the day the begining oestral activity and the weight on this day. The age and the weight on the day of vaginal opening are inherited additively. It is demonstrated that the females of BALB/c and C3H/He (mammary tumour susceptible strains) are characterized by higher rate of sexual maturation than those of C57BL/6 and AKR/J in which the tumours of this localization are rare.

D003433	Crosses, Genetic	Deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent. The parent organisms must be genetically compatible and may be from different varieties or closely related species.	Cross, Genetic,Genetic Cross,Genetic Crosses

D005838	Genotype	The genetic constitution of the individual, comprising the ALLELES present at each GENETIC LOCUS.	Genogroup,Genogroups,Genotypes
D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
