If a mutation has no effect on the fitness of individuals, the frequency of the mutant in the population will be determined by stochastic factors [a subject thoroughly dealt with by Wright (1969)]. On the other hand, where significant amounts of genetic variation affecting f

Practicality of the Theoretical Frameworks, deals with the possibilities of using these characters in estimates of monocotyledon phylogeny. Various hypotheses of monocotyledon evolution and phylogeny are discussed in the light of our current knowledge of characters, and some theoretical and practical problems in cladistic analysis of monocot

Essential Techniques in Elbow Surgerylthough their geographic distributions differ (Dobzhansky and Epling, 1944), as do their local spatial, feeding, and temporal preferences (Dobzhansky, 1951; Dobzhansky .., 1956), members of these two species do nevertheless encounter one another where they occur sympatrically. They can, for example,

Because of such problems and the small number of living species, morphoclines are rare, further complicating the efforts of the comparative morphologist (Hecht and Malone, 1972).
