^a Genotypes of 179 progeny were determined by PCR. Homozygous (Hom), heterozygous (Het), and wild type (WT) refer to the genotypes at the ANP2 and ANP3 loci. For example, “Homo; WT” indicates that the plant was homozygous for one of the mutations and wild type at the other locus. Expected values for the given genotype combinations were calculated using the observed allele frequencies for this experiment.
