Individually inherited traits, corresponding to regions in the DNA sequence, are called <a title="Genes" href="http://en.wikipedia.org/wiki/Genes"><font color="#0066cc">genes</font></a>.

Their double-helix model paired a sequence of nucleotides with a &quot;complement&quot; on the other strand. This structure not only provided a physical explanation for information, contained within the order of the nucleotides, but also a physical mechanism for duplication through separation of strands and the reconstruction of a partner strand based on the nucleotide pairings. They famously observed this in their paper, stating: <em>&quot;It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.&quot;</em></p><p>In the following decades, an explosion of research based on this understanding of the molecular nature of DNA became possible. The development of <a title="DNA sequencing" href="http://en.wikipedia.org/wiki/DNA_sequencing"><font color="#0066cc">DNA sequencing</font></a> in 1977 enabled the determination of nucleotide sequences on DNA,<sup class="reference" id="_ref-sanger_sequencing_0"><a title="" href="http://en.wikipedia.org/wiki/Genetics#_note-sanger_sequencing"><font color="#0066cc">[7]</font></a></sup> and the <a title="PCR" href="http://en.wikipedia.org/wiki/PCR"><font color="#0066cc">PCR</font></a> method developed by <a title="Kary Banks Mullis" href="http://en.wikipedia.org/wiki/Kary_Banks_Mullis"><font color="#0066cc">Kary Banks Mullis</font></a> in 1983 allowed the isolation and amplification of arbitrary segments of DNA.

<p>Classical genetics consists of the techniques and methodologies of genetics that predate the advent of <a title="Molecular biology" href="http://en.wikipedia.org/wiki/Molecular_biology"><font color="#0066cc">molecular biology</font></a>. After the discovery of the genetic code and such tools of <a title="Clone (genetics)" href="http://en.wikipedia.org/wiki/Clone_%28genetics%29"><font color="#0066cc">cloning</font></a> as <a title="Restriction enzyme" href="http://en.wikipedia.org/wiki/Restriction_enzyme"><font color="#0066cc">restriction enzymes</font></a>, the avenues of investigation open to geneticists were greatly broadened. Some classical genetic ideas have been supplanted with the mechanistic understanding brought by molecular discoveries, but many remain intact and in use, such as <a title="Mendelian inheritance" href="http://en.wikipedia.org/wiki/Mendelian_inheritance"><font color="#0066cc">Mendel's laws</font></a> and <a title="Muller's morphs" href="http://en.wikipedia.org/wiki/Muller%27s_morphs"><font color="#0066cc">Muller's morphs</font></a>.

<p>Behavioral genetics studies the influence of varying genetics on animal behavior. Behavioral genetics studies the effects of human disorders as well as its causes. Behavioral genetics has yielded some very interesting questions about the evolution of various behaviors, and even some fundamental principles of evolution in general. For example, guppies and meerkats seem to be genetically driven to post a lookout to watch for predators. This lookout stands a significantly slimmer chance of survival than the others, so because of the mechanism of <a title="Natural selection" href="http://en.wikipedia.org/wiki/Natural_selection"><font color="#0066cc">natural selection</font></a>, it would seem that this trait would be lost after a few generations. However, the gene has remained, leading evolutionary philosopher/scientists such as <a title="Richard Dawkins" href="http://en.wikipedia.org/wiki/Richard_Dawkins"><font color="#0066cc">Richard Dawkins</font></a> and <a title="W. D. Hamilton" href="http://en.wikipedia.org/wiki/W._D._Hamilton"><font color="#0066cc">W. D.

The interactions and behaviors of gregarious creatures is partially genetic in cause and must therefore be approached by evolutionary theory.</p>

<p>Molecular genetics builds upon the foundation of classical genetics but focuses on the structure and function of genes at a <a title="Molecule" href="http://en.wikipedia.org/wiki/Molecule"><font color="#0066cc">molecular</font></a> level. Molecular genetics employs the methods of both classical genetics (such as <a title="Hybridization" href="http://en.wikipedia.org/wiki/Hybridization"><font color="#0066cc">hybridization</font></a>) and <a title="Molecular biology" href="http://en.wikipedia.org/wiki/Molecular_biology"><font color="#0066cc">molecular biology</font></a>.

<dl><dd><em>Main articles:</em> <a title="Population genetics" href="http://en.wikipedia.org/wiki/Population_genetics"><font color="#0066cc">Population genetics</font></a>, <a title="Quantitative genetics" href="http://en.wikipedia.org/wiki/Quantitative_genetics"><font color="#0066cc">Quantitative genetics</font></a>, <a title="Ecological genetics" href="http://en.wikipedia.org/wiki/Ecological_genetics"><font color="#0066cc">Ecological genetics</font></a> </dd></dl>
<p>Population, quantitative and ecological genetics are all very closely related subfields and also build upon classical genetics (supplemented with modern molecular genetics). They are chiefly distinguished by a common theme of studying <a title="Population" href="http://en.wikipedia.org/wiki/Population"><font color="#0066cc">populations</font></a> of organisms drawn from nature but differ somewhat in the choice of which aspect of the organism on which they focus. The foundational discipline is population genetics which studies the distribution of and change in <a title="Allele frequency" href="http://en.wikipedia.org/wiki/Allele_frequency"><font color="#0066cc">allele frequencies</font></a> of genes under the influence of the four evolutionary forces: <a title="Natural selection" href="http://en.wikipedia.org/wiki/Natural_selection"><font color="#0066cc">natural selection</font></a>, <a title="Genetic drift" href="http://en.wikipedia.org/wiki/Genetic_drift"><font color="#0066cc">genetic drift</font></a>, <a title="Mutation" href="http://en.wikipedia.org/wiki/Mutation"><font color="#0066cc">mutation</font></a> and <a title="Migration" href="http://en.wikipedia.org/wiki/Migration"><font color="#0066cc">migration</font></a>. It is the theory that attempts to explain such phenomena as <a title="Adaptation (biology)" href="http://en.wikipedia.org/wiki/Adaptation_%28biology%29"><font color="#0066cc">adaptation</font></a> and <a title="Speciation" href="http://en.wikipedia.org/wiki/Speciation"><font color="#0066cc">speciation</font></a>.</p>
<p>The related subfield of quantitative genetics, which builds on population genetics, aims to predict the response to <a title="Selection" href="http://en.wikipedia.org/wiki/Selection"><font color="#0066cc">selection</font></a> given data on the <a title="Phenotype" href="http://en.wikipedia.org/wiki/Phenotype"><font color="#0066cc">phenotype</font></a> and relationships of individuals. A more recent development of quantitative genetics is the analysis of <a title="Quantitative trait loci" href="http://en.wikipedia.org/wiki/Quantitative_trait_loci"><font color="#0066cc">quantitative trait loci</font></a>. Traits that are under the influence of a large number of genes are known as quantitative traits, and their mapping to a location on the <a title="Chromosome" href="http://en.wikipedia.org/wiki/Chromosome"><font color="#0066cc">chromosome</font></a> requires accurate phenotypic, pedigree and marker data from a large number of related individuals.</p>
<p>Ecological genetics again builds upon the basic principles of population genetics but is more explicitly focused on <a title="Ecology" href="http://en.wikipedia.org/wiki/Ecology"><font color="#0066cc">ecological</font></a> issues. While molecular genetics studies the structure and function of genes at a molecular level, ecological genetics focuses on wild populations of organisms, and attempts to collect data on the ecological aspects of individuals as well as molecular markers from those individuals.</p>
<p>Population genetics is closely linked with the methods of genetic epidemiology. One method to study gene-disease associations is using the principle of <a title="Mendelian randomization" href="http://en.wikipedia.org/wiki/Mendelian_randomization"><font color="#0066cc">Mendelian randomization</font></a>.</p>

<p>A more recent development is the rise of <a title="Genomics" href="http://en.wikipedia.org/wiki/Genomics"><font color="#0066cc">genomics</font></a>, which attempts the study of large-scale genetic patterns across the <a title="Genome" href="http://en.wikipedia.org/wiki/Genome"><font color="#0066cc">genome</font></a> for (and in principle, all the DNA in) a given species. The field typically depends on the availability of whole genome sequences, computational tools and <a title="Sequence profiling tool" href="http://en.wikipedia.org/wiki/Sequence_profiling_tool"><font color="#0066cc">Sequence profiling tool</font></a> using <a title="Bioinformatics" href="http://en.wikipedia.org/wiki/Bioinformatics"><font color="#0066cc">bioinformatics</font></a> approaches for analysis of large sets of data.</p>

<p>The science which grew out of the union of <a title="Biochemistry" href="http://en.wikipedia.org/wiki/Biochemistry"><font color="#0066cc">biochemistry</font></a> and genetics is widely known as <a title="Molecular biology" href="http://en.wikipedia.org/wiki/Molecular_biology"><font color="#0066cc">molecular biology</font></a>. The term &quot;genetics&quot; is often widely conflated with the notion of <a title="Genetic engineering" href="http://en.wikipedia.org/wiki/Genetic_engineering"><font color="#0066cc">genetic engineering</font></a>, where the DNA of an organism is modified for some kind of practical end, but most research in genetics is aimed at understanding and explaining the effect of genes on phenotypes and in the role of genes in populations (see <a title="Population genetics" href="http://en.wikipedia.org/wiki/Population_genetics"><font color="#0066cc">population genetics</font></a> and <a title="Ecological genetics" href="http://en.wikipedia.org/wiki/Ecological_genetics"><font color="#0066cc">ecological genetics</font></a>), rather than genetic engineering.</p>
