^aThe parental type highlighted in bold font is the parental type from which the meiotic progeny inherited the mitochondria.

^bOnly nine of the >20 basidia that were dissected for crosses between CBS6039 and CBS6273 are shown here.

^cBasidia numbers 8 and 9 inherited mito-a from the A1B1 parental strain, CBS6039.
