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.

Assortative mating and disassortative mating
1995Assortative mating occurs if the plants mating resemble each other more, with regard to some trait, than would be the case for a pair of random plants. It implies a positive phenotypic correlation for the trait involved between the mating plants. The genotypes of these plants for the loci controlling the expression for the trait will therefore tend to ...

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.

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.
