The assumptions underlying the use of the Poisson distribution are essentially that the probability of an event is small but nearly identical for all occurrences and that the occurrence of an event does not alter the probability of recurrence of such events. These assumptions do not seem to be met for evolutionary events since (i) the probability of fixing(More)
Protein polymorphisms presumed to have a genetic basis are known to exist in natural populations of most species examined to date. Among protein morphs, the observed differences usually are detected as electrophoretic mobility changes that are assumed to be due to amino acid substitutions rather than to posttranslational modification. Since the studies of(More)
Allelic frequencies and genotypic distributions in three polymorphic enzyme systems demonstrated genetic differentiation over extraordinarily short distances in a population of black pineleaf scale insects infesting ponderosa pine trees. A hierarchical analysis of the population genetic structure showed significant differences between demes on different(More)
Genetic structuring in a natural population requires either: (a) a sedentary habit permitting demic sub-units of small effective population size to differentiate under the influence of random drift; or (b) locally variable selection of sufficient intensity to override the homogenising effects of gene flow. Wright (1931) showed that drift cannot sustain(More)
A study of glycoasminoglycans (GAGs) in dentinogenesis imperfecta Type I (DI I) revealed increased GAG in DI I EDTA soluble dentin as compared to controls. EDTA insoluble GAG contained less GAG than age-matched controls. The role of GAG in dentin pathosis is discussed.
