A test for cytoplasmic organelle
mutations (eg. mitochondrial or chloroplast mutations), based on new
associations (recombination) of phenotypes in cells derived from genetically
marked haploid heterokaryons. Since the heterokaryons are haploid
and produce haploid spores by a process that does not involve diploid
nuclei normal genetic recombination does not occur. Therefore evidence
of recombination is evidence of reassociation by some other means
such as reassociation of an organelle with nucleus. |
