A genomic DNA digest (DraI) of P. squamulatum (first lane of apomicts), P. glaucum (first lane of sexuals), and eight F1 individuals of each reproductive phenotype probed with ugt197 (A), C4–600 (B), Q8M-800 (C), A14M-200 (D), and O7M-600 (E). The same blot was stripped and reprobed with each sequence. All probes detected either hemizygous (A–D) or polymorphic (E) DNA sequences in the apomictic individuals. None of the probes hybridized with bands of the same molecular weight.
