For the production of transgenic rats, matings are carried out under controlled conditions in order to obtain a supply of one-cell fertilized eggs, and to obtain pseudopregnancy in females, which will act as surrogate mothers for the microinjected eggs.

Veterinary Clinics of North America: Food Animal Practice, 1992
The mating management of pigs is conducted under a wide spectrum of management techniques because females are variously hand-mated, pen-mated, or artificially inseminated. Factors that may affect the onset of estrus when hand-mating are boar exposure, method of housing females after weaning, season, type of facilities, and parity.

Mating type and mating strategies in Neurospora
BioEssays, 1990AbstractIn the heterothallic species Neurospora crassa, strains of opposite mating type, A and a, must interact to give the series of events resulting in fruiting body formation, meiosis, and the generation of dormant ascospores. The mating type of a strain is specified by the DNA sequence it carries in the mating type region; strains that are ...

In the process of creating and analyzing transgenic mice, matings between male and female animals are required for the following reasons: 1. To produce fertilized one-cell eggs for microinjection. Natural matings between mature females (over 6-7 wk of age) and stud males (over 7-8 wk of age) can be used to supply the one-cell eggs.

The Influence of the Ideal Mate Image on Mate Selection and Mate Perception
Journal of Marriage and the Family, 1965This study attempted to determine whether ideal mate images actually influence mate selection. The mate perceptions of 90 engaged persons were compared with the ideal mate conceptions of single, unengaged persons precision-matched to the engaged individuals on personality characteristics. Analysis of personality and perception correlation matrices lead

Preferential mating. Nonrandom mating of a continuous phenotype
Theoretical Population Biology, 1976Abstract A phenotypically determined nonrandom mating model is specified for a continuous trait controlled by a major gene. The distribution of phenotypic preferences of any particular individual choosing a mate may be specified in terms of the phenotype of the individual.

Defense of Mate and Mating Chamber in a Wood Roach
Science, 1964Studies of the eastern wood roach, Cryptocercus punctulatus , reveal that, under laboratory conditions, the mating chambers in rotten wood are inhabited by mated pairs, the male of which will usually defend the chamber successfully against intruding males by a form of fighting.
