Maintenance of genetic variation in apomictic plant populations

Genetic Variation and Inheritance of Early Growth Characteristics in Three Wild Pistachio Populations

Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

Genetic Variation Within PoPulations

Seven microsatellite loci were used to develop multilocus genotypes for 49 individuals of Neotoma stephensi (Stephen’s woodrat) collected from nine sites in central and northern Arizona. Several statistical analyses were used to determine genetic structure, levels of genetic variability, and degree of relatedness. Structure analyses estimated two distinct groups within localities. The FST value...

Patterns of Molecular Variation in Plant Populations

It has recently been argued [8], [9] that rate of evolution at the molecular level is greater than can be accounted for by natural selection and hence that a large part of observed molecular changes must be selectively neutral. This discussion will be concerned with some experimental results, from studies of a number of different species of plants, that bear on this question. These results will...

ORIGIN AND MAINTENANCE OF GENETIC VARIATION IN BLACK CARm POPULATIONS OF ST. VINCENT AND CENTRAL AMERICA

The Black Caribs of Central America (also known as the Gariftma) provide " tropical example of an evolutionarily successful colonising population.
