  • a The null hypothesis tested is that P1-rr segregates unchanged from the mop1-1 homozygote at 50% frequency. Orange and patterned ears were combined for χ2 calculations. If P1-rr had paramutated to P1-rr′ in a previous generation, an excess of patterned ears would be expected; this was not observed.
