A COMPARATIVE STUDY OF THE SERUM PROTEINS OF THE SPECIES OF TARICHA AND THEIR HYBRIDS

Spontaneous Hybridization in Cottidae

“…The same condition is described in various groups of animals, e.g. in birds (BRANDT, SMITH, ANDREWS and CLEGG, 1952), toads (Fox, DESSAUER and MAUMUS, 1961), turtles (CREN-SHAW, 1965), fishes (NYMAN, 1965 a ) and salamanders (COATES, 1967). Blood-serum proteins dyed with Amido Black often show similarities between closely related species of fish (NYMAN, 1965 a ) .…”

Electrophoresis of Proteins in Natural Populations of Partula (Gastropoda)

“…A number of electrophoretic studies of the interrelationships of natural populations have been carried out with egg albumen and serum proteins of vertebrates (Brandt et al, 1952;Zweig and Crenshaw, 1957;Fox et al, 1961;Dessauer et al, 1962;Manwell et al, 1963;Crenshaw, 1965;Coates, 1967). The present investigation shows that the electrophoretic separation of tissue proteins can also shed light on the relationships in invertebrates.…”

Analysis of Enzyme Variation in Natural Populations of the Butterfly Colias eurytheme

“…Second, different alleles may produce bands that are very close together. Many of the alternative band positions presented as allelic variants in the current literature are separated by a distance less than 5% of the migration path of the sample (8)(9)(10)(11)(12), while the experimental variability in a given band position that may be encountered in surveys of natural populations often approaches or exceeds 5% of the gel path (12)(13)(14)(15)(16). In the face of this variability, it is mandatory to have some measure of the extent to which observed variations in band position are caused by experimental variables rather than by intrinsic differences between the proteins.…”
