Look back at Figure 16.12. If you crossed an F2 offspring to a homozygous B-I B-I plant, what phenotypic results would you expect for the F3 offspring?

Figure 16.12:

Cross strain A to strain B B' B' x B-I B-I Green stalks and husks F offspring BB' Purple stalks and husks All F, offspring inherit a B' allele from strain A, and a B-I allele from strain B. The B-I allele is converted to B' by a paramutation. Green stalks and husks Cross F, offspring to strain B: B' B x B-I B-I Green stalks and husks Purple stalks and husks F offspring inherit either a B' or B' allele from the F parent on the left, and a B-I allele from the strain B parent on the right. In both cases, a paramutation converts the B-I allele to B'. F offspring: B' B or B' B Green stalks and husks Green stalks and husks
