title: Spontaneous segregation of a heterozygous diploid of Aspergillus niger.
abstract: A case of spontaneous segregation of a heterozygous diploid was observed with Aspergillus niger, giving rise to a somatic recombinant. Assuming an independence of markers, its genotype is suggested to be brw+lys pab+brw lys+pab.
