Agglutinative mating types ofSaccharomyces transvaalensis

Antonie van Leeuwenhoek, 1973
Agglutinative mating types ofSaccharomyces transvaalensis have been recovered from the type strain of this species. These mating types react with the corresponding opposite mating types obtained from two other strains of this species but do not react with one-spore cultures of the physiologically similar species,Saccharomyces dairensis.

Analysis of ABO Mating Type Frequencies

Human Heredity, 1974
Recently, a new model has been proposed called the generalized Wright’s model (GWM). The GWM involves (k–1)(k + 2)/2 number of independent parameters for any k-allelic system; out of these, k–1 are gene frequencies and k(k–1)/2 are partial fixation indices, also called partial inbreeding coefficients.

Directionality of yeast mating-type interconversion

Cell, 1982
The mating-type a and alpha alleles of the yeast Saccharomyces cerevisiae interconvert by a transposition-substitution reaction where replicas of the silent mating loci, at HML and HMR, are transmitted to the expressed mating-type locus (MAT). HML is on the left arm and HMR on the right arm, while MAT is in the middle of chromosome III.

Mating Types and Mating Type Inheritance in Euplotes minuta Yocom (Ciliata, Hypotrichida)

The Journal of Protozoology, 1966
SYNOPSIS. Thirty‐one stocks of a marine ciliate, Euplotes minuta Yocom, collected from different localities, can be grouped in seven mating types. True pairs are formed only in mixtures of stocks belonging to different mating types. No selfing pairs or intraclonal conjugation have ever been observed.

Mating types in cellular slime molds

Biochemical and Biophysical Research Communications, 1973
Abstract We have discovered mating types in three species of cellular slime mold. One of these species is Dictyostelium discoideum , hitherto the subject of extensive biochemical investigations, and now amenable to genetic studies.

Mating-Type Inheritance

1988
Discovery of mating type in Paramecium (Sonneborn 1937) was the first demonstration of sex in unicellular animals. Initial genetic studies showed peculiar modes of mating-type inheritance, which were subsequently traced to macro-nuclear differentiations in which genes controlling the potentiality of the expression of mating type were repressed or ...

Mating-Type Substances

1988
Conjugation in Paramecium is initiated by a highly specific cell-cell recognition and adhesion event referred to as the mating reaction (Sonneborn 1937). The term “mating-type substances” was first introduced by Metz (1946, 1948, 1954) to define substances or molecular configurations on the cell surface that mediate the mating reaction.

Minority type human mate preference

Biodemography and Social Biology, 1983
Abstract Male and female students were asked to select from photographs projected on slides the individual they would most prefer as a mate in a long‐term husband‐wife relationship. Frequencies of contrasting hair color, facial expression, and profile types were varied on the slides to determine whether a minority‐type advantage occurred.
