Frequency of pollen phenotypic classes in gem2

	Normal	divided	uninucleate	aborted
Wt (+/+)	99.5	-	-	0.5
gem2 (+/gem2)	87.3	4.2	4.1	4.4

Counts were made on three heterozygous gem2 plants: Wt = No-O ecotype. Normal = trinucleate pollen with one vegetative and two sperm nuclei; divided = partially or completely divided pollen with one nucleus or two unequal nuclei (includes < 0.3 % undivided binucleate pollen); uninucleate = single large nucleus; aborted = collapsed pollen with no visible nuclei. Data was derived from >1000 spores.
