EFFECTS OF GLUCOSE REPRESSION ON THE TRANSMISSION AND RECOMBINATION OF MITOCHONDRIAL GENES IN YEAST (SACCHAROMYCES CEREVISIAE)

Matings of a number of Saccharomyces cerevisiae stocks
give different output ratios of mitochondrial genotypes depending on whether
the cells are glucose-repressed or derepressed. The effects of glucose repression
are independent of cellular mating type and mitochondrial genotype, and take
place at least in part after zygotes are formed. An explanation is proposed
in terms of changes in the relative numbers of mitochondrial DNA molecules
contributed by the a and 
parents, modified by selective replication
or destruction of molecules inside the zygote.
