It can be roughly divided into four major areas. There are topics within each of these subfields that every biology student should be familiar with. Genetics is a relatively new and broad field. It can be roughly divided into four major areas. There are topics within each of these subfields that every biology student should be familiar with. * Classical (Transmission) Genetics (e.g., Mendelian crosses, dominance, sex-linkage,​ linkage, recombinant mapping (Poisson distribution and Haldane'​s correction),​ epistatsis, morphs, genetic dissection, complementation,​ pedigree analysis (and autozygosity),​ chi-square testing, meiotic drive) * Classical (Transmission) Genetics (e.g., Mendelian crosses, dominance, sex-linkage,​ linkage, recombinant mapping (Poisson distribution and Haldane'​s correction),​ epistatsis, morphs, genetic dissection, complementation,​ pedigree analysis (and autozygosity),​ chi-square testing, meiotic drive) - * Molecular Genetics (e.g., the central dogma, codon tables, gene structure, gene regulation, LOD score mapping, epigenetics,​ X-inactivation,​ imprinting, cell cycle control, cancer genetics, gain-of-function and loss-of-function mutations, ancient DNA, transposable elements) + * Molecular Genetics (e.g., the central dogma, directionality, codon tables, gene structure, gene regulation, LOD score mapping, epigenetics,​ X-inactivation,​ imprinting, cell cycle control, cancer genetics, gain-of-function and loss-of-function mutations, ancient DNA, transposable elements, plasmids, restriction enzymes, transgenesis,​ PCR, sequencing) - * [[Population Genetics]] (inbreeding,​ $F_{ST}$ and migration rates, effective population size, the coalescence of two lineages, neutral mutations and the rate of evolution, balancing selection, directional selection, purifying selection and genomic mutation rates) + * [[Population Genetics]] (effective population size, inbreeding, $F_{ST}$ and migration rates, the coalescence of two lineages, neutral mutations and the rate of evolution, balancing selection, directional selection, purifying selection and genomic mutation rates) * Quantitative Genetics (e.g., binomial and normal distributions,​ heritability,​ regression, the breeder'​s equation, GWAS, gene-environment interactions,​ relative risk, heritability evolving) * Quantitative Genetics (e.g., binomial and normal distributions,​ heritability,​ regression, the breeder'​s equation, GWAS, gene-environment interactions,​ relative risk, heritability evolving) Teaching topics like recombinant mapping, population genetics, heritability,​ and epistasis is not as directly important to the modern general practice of genetics. However, it is valuable in that it shows the power of logic and inference to use observations to construct models of how the system works beyond the immediately observable surface of things. Geneticists used logical inference to map out biochemical pathways, map genes onto chromosomes,​ determine that behaviors were composed of both genetic and non-genetic influences, and infer natural selection acting upon genetic variants, long before it was possible to study these processes at a molecular DNA sequence variant level. The demonstrated power of logic, observation,​ inference, and model building is a valuable lesson to anyone working in any field. ​ Teaching topics like recombinant mapping, population genetics, heritability,​ and epistasis is not as directly important to the modern general practice of genetics.
