Table 1.
Mating Type− Parent | Mating Type+ Parent | Resulting Strain |
tca1-8 | mca1-6 | mt |
mt | mH | mHt |
mt | tF | mtF |
mH | {ccsA-B6} | mH {ccsA-B6}a |
Due to the uniparental inheritance of the chloroplast genome from the mt+ parent strain, each member of the resulting tetrads carried the chloroplast mutation ccsA-B6, while the two nuclear loci mca1-8 and MCA1-HA showed independent Mendelian segregation.
