Randomness of nuclear distribution in conidia ofNeurospora heterokaryons

  • Deana T. Klein
Article

Summary

  1. 1.

    Random distribution of nuclei in the macroconidial populations of heterokaryons ofNeurospora crassa has been shown.

     
  2. 2.

    Randomness is unaffected by either the genotype of mutants constituting the heterokaryon or by an increase in the relative proportions of homokaryotic conidia.

     
  3. 3.

    The estimates of nuclear frequency as determined by two different statistical methods were in very close agreement.

Zusammenfassung

  1. 1.

    Die Zufallsverteilung von Kernen in der Makrokonidien-Population der Heterokarya vonNeurospora crassa wird gezeigt.

     
  2. 2.

    Der Grad der Zufallsverteilung ist sowohl durch die Genotypen der Mutanten, die das Heterokaryon bilden, als auch durch die Zunahme der relativen Menge von homokaryotischen Konidien nicht beeinflußt.

     
  3. 3.

    Die Verteilungsrate der beiden Kerntypen wurde mittels zweier verschiedener statistischer Methoden bestimmt; die Werte sind in sehr guter Übereinstimmung.
