Cladistics

... trees. However, by and large the phylogenetic approach to systematics has proven useful and coherent and has gained general support. As DNA sequencing has become easier, phylogenies are increasingly often constructed with the aid of molecular data. Computational systematics allows the use of ...

Endosymbiont

An EST is produced by one-shot sequencing of a cloned mRNA , and the resulting sequence is a relatively low quality fragment whose length is limited by current technology to approximately ...

Glycomics

Isozyme

... Molecular markers for this purpose. Although they have now been largely superseded by more informative DNA -based approaches (such as direct DNA sequencing , Single nucleotide polymorphisms and microsatellites ), they are still amongst the quickest and cheapest marker systems to develop, and remain ...

Phenotype

... enable prediction of the phenotype. Nevertheless, because phenotypes are much easier to observe than genotypes (it doesn't take chemistry or sequencing to determine a person's eye color), classical genetics uses phenotypes to deduce the functions of genes. Breeding experiments can then check these ...
