The number of matings was studied in order to determine the male preference.
Where heteroallelic interactions were studied for phenotypic analysis, matings between strains were carried out at 25° using reciprocal crosses.
In several species of fungi, the properties of the chromosomal region surrounding the mating-type locus have been studied extensively because of their similarities to the sex chromosomes of other organisms (Fraser and Heitman 2004, 2005).
For instance, parasitoid mating systems have typically been studied in terms of how mating structure affects sex allocation.
Among the properties whose inheritance was studied were mating-type variations, serotype variations, and the structural or "surface inheritance" of ciliary structures.
The mating behavior of longicornis- vitripennis hybrid males has been studied previously.
Blaustein, who was studying the mating behavior of frogs and toads in the Cascade Mountains, had observed that some long-standing populations simply weren't there anymore.
Senior author Libiao Zhang, a biologist at Guangdong Entomological Institute in Guangzhou, China, and colleagues had been studying the mating behavior of the short-nosed fruit bat (Cynopterus sphinx), which is native to southeast Asia.
However, in all these studies, matings were arranged and it is not known whether multiple paternity provides indirect, genetic benefits when females are able to select their own mates though the benefits may be even greater compared to when females are forced to mate with randomly selected males in terms of quality.
For fecundity studies, timed matings were performed with young 8-12-week-old virgin female WT and Dgat1−/− mice and proven male breeders.
