Debate over what is a species was already considered old hat when Darwin wrote his seminal abstract (as he called it) more than 150 years ago.1 Endless papers, workshops, and symposia have been presented in an effort to "solve" the species problem. Yet, here we are, at it again. Has there been any progress? I believe that there has been, and that among

This chapter looks at empirical methods for quantifying gene flow and inferring its role in adaptive divergence. An important point made therein is that gene flow can sometimes aid adaptation, such as when it enhances the genetic variation on which selection acts.

By comparing potential and actual risks in both fields of agriculture, with or without GMOs, we need a clear view of the similarities and differences. Raamsdonk (1993) has given a scheme of gene flow, whether natural or influenced by human activity.

Theoretical and Applied Genetics, 2003
A survey of Australian cherry orchards identified the cherry cultivars Sunburst, Summit, Merchant, Sam, Sylvia, Tieton, Kordia, Regina, Empress, Nordwunder and Ulster as having low fruit-set associated with poor pollination. Unique orchard sites across Australia where low fruit-set was not a problem for these cultivars were located, and pollen gene ...

In this chapter, we first present characteristics of carrots that will affect gene flow and discuss dispersal via pollen by insect pollinators and via seeds by wind and animals. Although carrot is often referred to as a biennial, we introduce the various life history strategies observed in wild carrot populations as these can impact population growth ...

There is a concern that genes may flow from genetically modified organisms (GMOs) to sexually compatible relatives (vertical gene flow) and to totally unrelated species and families of organisms (horizontal gene flow). This concern is based on an entirely erroneous feeling that cloned genes are intrinsically more likely to be involved in horizontal ...

Gene flow is the movement of genes between different gene pools (Endler, 1977; Slatkin, 1985). This primarily includes movement of genes among individuals within separated populations or subpopulations. It can be extended to include movement of genetic elements between taxa (i.e., introgression). The factors affecting gene flow are environmental (e.g.,
