Analysis of ABO Mating Type Frequencies
Human Heredity, 1974Recently, 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.

Mating types in cellular slime molds
Biochemical and Biophysical Research Communications, 1973Abstract 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.

Directionality of yeast mating-type interconversion
Cell, 1982The 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, 1966SYNOPSIS. 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.

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.

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 agglutination of cilia detached from complementary mating types of Paramecium
Experimental Cell Research, 1974Abstract Cell-free preparations of mating-reactive cilia were obtained from complementary mating types of Paramecium caudatum with the treatment of the cells in a Triton X-100 solution and then in a Ca solution. When the cilia from both mating types thus obtained were mixed, strong agglutination was observed.

Current Genetics, 2007
Sexual reproduction of fungi is governed by genes located on the mating-type (MAT) locus. To analyze the MAT locus of the genus Diaporthe (anamorph: Phomopsis), a large genera within the ascomycetous class Sordariomycetes, we cloned and sequenced loci MAT1-1 and MAT1-2 from two heterothallic Diaporthe species, designated as Diaporthe W- and G-types ...

Mating type loci inFusarium: structure and function
Mycotoxin Research, 2006Sex in fungi is regulated by highly dissimilar mating type loci named idiomorphs. The genus Fusarium harbours both sexual as well as esexual species and each appears to contain one or the other idiomorph. The structure of these loci is highly conserved, suggesting a cryptic sexual cycle in these socalled asexual species. Alternatively, idiomorphs could
