Most recently my laboratory has examined the nature, quantity and mode of distribution of DNA genomes of mitochondria and plastids. The second area of laboratory concentration concerns the species problem, how separate species evolve. The work examines particular species and genera of the volvocales, freshwater green algae, brown algae, and abalones, and the analysis includes mating compatibility, chromosome number, and DNA relatedness as determined by sequencing.
