Any process that results in a change in the behavior of an organism as a result of a nutrient stimulus.

Any biological process involved in the maintenance of the steady-state number of cells within a population of cells in the meristem.

Any process that establishes and transmits the specification of mating type upon an individual. Mating types are the equivalent in microorganisms of the sexes in higher organisms.

The conversion of a single-cell organism from one mating type to another by the precise replacement of a DNA sequence at the expressed mating type locus with a copy of a sequence from a donor locus.

The process that determines which donor locus a cell uses, in preference to another, in mating type switching.

The conversion of the mating-type locus from one allele to another resulting from the recombinational repair of a site-specific double-strand break at the mating-type locus with information from a silent donor sequence. There is no reciprocal exchange of information because the mating-type locus copies information from the donor sequence and the donor sequence remains unchanged.

The inactivation of recombination at sequences around a mating type donor locus, with the consequence that the other donor is the only one available for mating type switching; exemplified by the HML locus and surrounding sequences on Chromosome III in Saccharomyces cerevisiae.

The activation of recombination at a mating type locus, such that it is used in preference to the other donor locus for mating type switching; exemplified by the HML locus and surrounding sequences on Chromosome III in Saccharomyces cerevisiae.

The transmission of information about sexual status from the initial, general, determination to signals specific to the soma.

The sex determination process that results in the initial specification of sexual status of an individual organism.

The developmental process in which an organism senses the number of X chromosomes and autosomes in its genomic complement and responds to it.

The developmental process in which an organism interprets its X to autosomal chromosomal complement.

The process that mediates the interactions between somatic cells and gonadal cells that ultimately results in the specification of sexual status of the organism.

The events determining the somatic sexual phenotype after the initial transmission of that phenotype to soma-specific information pathways.

The sex determination processes that take place after the initial transmission of the sexual phenotype to specific information pathways.

The establishment of the sex of an organism by physical differentiation.

The events determining the germ-line sexual phenotype after the initial transmission of that phenotype to germ-line-specific information pathways.
