“…The proportion of heterocaryotic conidia isolated from all heterocaryons indicated that any deviation from random distribution was not extreme. However, as homocaryotic conidia are occasionally produced in excess of expectation (Atwood and Mukai, 1955;Klein, 1958), the nuclear frequencies given must be thought of as maximal estimates of pan nuclear frequency and will be denoted EMP.…”

Adaptation in Pantothenate‐requiring Neurospora Ii. Nuclear Competition During Adaptation

The process of adaptation in pantothenate-requiring Neurospora was studied by the use of heterocaryons constituted of the pan-I strain and a modified strain, pan-L m, derived from it. Although pan-I-m. homocaryons grow well on a pantothenate concentration on which pan-L grows little or not at all, pan-I nuclei often have a selective advantage in pan-I + pan-1-m heterocaryons grown on the same medium. This results in non-adaptive changes in nuclear ratios and labile growth rates of the heterocaryons. Nuclear competition does not occur when pantothenate is not limiting to the growth of either homocaryon. The results are discussed, and related to past work on adaptation and nuclear ratio changes in Neurospora hetercaryons.

“…In Phycomyces their correctness seems to be experimentally verified (Oerda-Olmedo & Reau, 1970) but in Neurospora the proportion of homokaryotic spores is, frequently, greater than expected (Atwood & Mukai, 1955;Klein, 1958). In Phycomyces their correctness seems to be experimentally verified (Oerda-Olmedo & Reau, 1970) but in Neurospora the proportion of homokaryotic spores is, frequently, greater than expected (Atwood & Mukai, 1955;Klein, 1958).…”

A computer simulation of the genetic analysis of the asexual life cycle of Phycomyces' heterokaryons has been carried out. We have studied experimentally the relationship between the nuclear proportion in heterokaryotic mycelia containing prototrophic and auxotrophic nuclei and their growth rates. We discuss possible evolutionary implications of heterokaryosis in coenocytic fungi and the genetic applications of the quantitative complementation technique.
