The study of hybrids and their evolutionary significance is often based on a number of tacit
assumptions regarding character expression in hybrids. This article examines …

Hybridization plays an important role in the evolution of many taxonomic groups, but large-
scale phylogenetic patterns of hybridization are poorly known. Here, we investigate patterns …

Hybridization is an important part of the evolutionary history of flowering plants. If
hybridization has occurred among the species of a taxon under cladistic analysis the results …

Genetic mapping methods provide a unique opportunity to study the interactions of
differentiated genes and genomes in a hybrid genetic background. After a brief discussion of …

Interspecific hybridization is considered common among plants, but the methods of cladistic
systematics produce only divergently branching phylogenetic hypotheses and thus cannot …

I examined three aspects of the cladistic treatment of a set of 17 F1 hybrids of known
parental origin:(1) impact of hybrids on consistency index (CI) and number of most …

One of the striking observations from the young field of molecular evolutionary biology has
been the high frequency of cases where taxon-specific markers are found to differ widely in …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …
