Figure 4.

Stained agarose gels showing genomic amplification products for the following three genes: (a) β-fructosidase, (b) myosin heavy chain and (c) thioredoxin M-type 1. Arrows indicate missing amplification products, which in all cases were of T. dubius–origin for the same two individuals (2892-5-1 and 2892-6-1). Diploid parental amplification products are shown on the left (T. dubius) and right (T. porrifolius) of each gel. The smallest and largest fragments of the size standard are annotated.
