Genetics and Genomics
Inheritance, variation, and genome-scale biology — from Mendelian traits to population-scale sequencing.
Genetics and Genomics sits within biology and addresses inheritance, variation, and genome-scale biology — from mendelian traits to population-scale sequencing. The page below sketches the conceptual scope of the area, the methodological tools it relies on, and the recent literature anchoring its current frontier.
The area organises around a small number of recurring axes: scope (what biological scales the work spans), method (the dominant experimental or computational tools), data regime (what kinds of measurements are now routine vs. still frontier), and open questions (what the field cannot yet do reliably). The sources below cover different combinations of these axes.
Foundational references
Strachan, Human Molecular Genetics is a standard reference for the foundations covered here, used across the field to anchor terminology, canonical models, and the relationships between sub-areas of genetics and genomics. Treat it as the entry point to which the more specialised work below adds frontier detail.
Hartwell, Genetics: From Genes to Genomes is a standard reference for the foundations covered here, used across the field to anchor terminology, canonical models, and the relationships between sub-areas of genetics and genomics. Treat it as the entry point to which the more specialised work below adds frontier detail.
Griffiths, Introduction to Genetic Analysis is a standard reference for the foundations covered here, used across the field to anchor terminology, canonical models, and the relationships between sub-areas of genetics and genomics. Treat it as the entry point to which the more specialised work below adds frontier detail.
Open questions
Open questions in genetics and genomics cluster around scaling current methods to larger systems, integrating measurements across modalities, and producing predictive rather than descriptive models. The references above mark the work that the next iteration of this page should engage with in more specific detail.
