Intersexual partial diploids of phycomyces.
Sexual interaction between strains of opposite sex in many fungi of the order Mucorales modifies hyphal morphology and increases the carotene content. The progeny of crosses of Phycomyces blakesleeanus usually include a small proportion of anomalous segregants that show these signs of sexual stimulation without a partner. We have analyzed the genetic constitution of such segregants from crosses...
متن کاملGenetic control of alkaline phosphatase synthesis in Neurospora: the use of partial diploids in dominance studies.
In wild-type Neurospora, alkaline phosphatase is made under conditions of phosphate limitation, but not conditions of phosphate sufficiency. Mutants at two unlinked loci, nuc-1 and nuc-2, do not make alkaline phosphatase under any conditions, while mutants at two quite closely linked loci, pcon and preg, make alkaline phosphatase even under conditions of phosphate sufficiency. pcon is extremely...
متن کاملIntersexual conflict in spiders
Reproductive strategies of males and females usually differ and. as a consequence, may impose asymmetric costs of reproduction on tire two sexes and result in conflict between the sexes. In spiders, males do not provide parental care and females can store sufficient sperm for several clutches. These characteristics define the stage for a conflict between males and females that occurs mainly ove...
متن کاملThe canonical equation of adaptive dynamics for Mendelian diploids and haplo-diploids.
One of the powerful tools of adaptive dynamics is its so-called canonical equation (CE), a differential equation describing how the prevailing trait vector changes over evolutionary time. The derivation of the CE is based on two simplifying assumptions, separation of population dynamical and mutational time scales and small mutational steps. (It may appear that these two conditions rarely go to...
متن کاملGlutamine synthetase subunit mixing and regulation in Bacillus subtilis partial diploids.
A specialized transducing phage, SP beta c2 dglnA2, of Bacillus subtilis was used to construct partial diploids with various glutamine auxotrophs. The overproduction of manganese-stimulated glutamine synthetase no longer occurred in the diploids. The kinetics of heat inactivation of the enzyme extracted from two diploids suggests that there was subunit mixing.
