Genetic diversity of local cattle*

open access: yesActa Biochimica Polonica, 2018
The Slovak Pinzgau breed faces the bottleneck effect and the loss of diversity due to unequal use of founders and significant population decline. Further population size reduction can lead to serious problems. High-throughput genotypes of 179 individuals were used to characterise genetic diversity and differentiation of Slovak Pinzgau, Austrian Pinzgau,

PCR amplification of a long rDNA segment with one primer pair in agriculturally important nematodes

open access: yesJournal of Nematology, 2019
Ribosomal DNA has been a reliable source of taxonomic and phylogenetic markers due to its high copy number in the genome and stable variation with few polymorphisms due to the homogenizing effect of concerted evolution.

Genetic diversity in introduced populations with Allee effect [PDF]

open access: yesarXiv, 2013
A phenomenon that strongly influences the demography of small introduced populations and thereby potentially their genetic diversity is the Allee effect, a reduction in population growth rates at small population sizes. We take a stochastic modeling approach to investigate levels of genetic diversity in populations that successfully overcame a strong ...

A genome-wide survey of genetic variation in gorillas using reduced representation sequencing [PDF]

open access: yes, 2013
All non-human great apes are endangered in the wild, and it is therefore important to gain an understanding of their demography and genetic diversity. To date, however, genetic studies within these species have largely been confined to mitochondrial DNA and a small number of other loci.

Genetic Diversity in a Soybean Collection

open access: yesCrop Science, 2009
Soybean [Glycine max (L.) Merr.] was domesticated in China, and cultivated landraces were initially distributed throughout Asia and more recently extended to Europe and America. Previous studies of genetic diversity suggest a strong genetic bottleneck between Asian and North American soybean genetic pools. However, little is known about the potentially

Molecular and morphological characterization of Avenae-group cyst nematodes (Heteroderidae) from Greece

open access: yesJournal of Nematology
Cyst nematodes of the genus Heterodera comprise 87 nominal species of economically important plant parasites, with the Avenae-group one of the largest, consisting of 12 species. Samplings for cyst nematode studies were carried out from multiple locations

Importance of Genetic Diversity Assessment in Crop Plants and Its Recent Advances: An Overview of Its Analytical Perspectives

open access: yesGenetics Research International, 2015
The importance of plant genetic diversity (PGD) is now being recognized as a specific area since exploding population with urbanization and decreasing cultivable lands are the critical factors contributing to food insecurity in developing world ...
