Propagule pressure plays an important role in species invasions (Groom, 2006). Charles Darwin was the first to study specific factors related to invasions of non-native species. In his research he identified that few members of the same genus were present in habitats containing naturalized non-indigenous species (Colautti et al., 2006).
The hapten label is recognized by anti-bodies, which in turn are coupled to a detectable signal (Gunderson et al. 2006). APEX-2 is an arrayed primer extension genotyping method which is able to identify hundreds of SNPs or mutations in parallel using efficient homogeneous multiplex PCR (up to 640-plex) and four-color single-base extension on a ...
HRM offers a faster and more convenient closed-tube method of assessing the presence of mutations and gives a result which can be further investigated if it is of interest. In a study carried out by Scott et al. in 2006, [4] 3 cell lines harbouring different BRCA mutations were used to assess the HRM methodology. It was found that the melting ...
Diversity Arrays Technology (DArT) is a high-throughput genetic marker technique that can detect allelic variations to provide comprehensive genome coverage without any DNA sequence information for genotyping and other genetic analysis.
Originally, genotyping was only used to confirm outbreaks of tuberculosis; but with the evolution of genotyping technology it is now able to do far more. Advances in genotyping technology led to the realization that many cases of tuberculosis, including infected individuals living in the same household, were not actually linked. [6]
Genotyping is testing that looks at specific variants in a particular area of the genetic code. This technology is limited only to those specific variants that the test is designed to detect. SNP genotyping is a specific form of genotyping. [31]
A wide range of methods have been developed to assess the structure of human populations with the use of genetic data. Early studies of within and between-group genetic variation used physical phenotypes and blood groups, with modern genetic studies using genetic markers such as Alu sequences, short tandem repeat polymorphisms, and single nucleotide polymorphisms (SNPs), among others.

In a study by Kim et al., genes linked to the obesity trait in both pigs and humans were discovered using comparative genomics and chromosomal heritability. [27] By using these two methods, the researchers were able to overcome the criticism that candidate gene studies are solely focused on prior knowledge.
