Parthenogenesis is a fairly common phenomenon in the animal kingdom, so that parthenogenetically reproducing forms occur in most animal groups. There is no need to enumerate all the groups in which parthenogenesis has been found; for detail

The advent of electrophoresis as a technique for the assessment of levels of polymorphism in populations has not provided the anticipated solution to this p

Perhaps even more important than its considerable analytical power and versatility, this approach has highly useful heuristic chara

Evolution of the Rust Fungi (Uredinales) as Reflected by Their Ecological Problems,an environment favorable to their plants. But a few groups, of which the rusts (Uredinales) are by far the largest, make no saprophytic growth in nature;. and they are therefore firmly tied, and generally closely adapted, to the environment of their hosts.
