Editors Reads Verdict
Mukherjee's ambitious history of genetics is as moving as it is informative. The interweaving of his family's mental illness history with the science of heredity gives the book an emotional depth rare in science writing.
What We Loved
- Integrates personal family history with the history of genetics in an unusual and powerful way
- The most comprehensive narrative history of genetics available for general readers
- The sections on CRISPR and genetic medicine are clear and important
- Mukherjee's scientific precision and narrative skill are both exceptional
Minor Drawbacks
- At 600 pages, it demands sustained commitment
- The personal narrative device works better in some sections than others
- The ethical questions about genetic manipulation are raised more than resolved
Key Takeaways
- → The gene is the fundamental unit of hereditary information and the key to understanding biology
- → The history of genetics is inseparable from the history of eugenics and its horrors
- → CRISPR represents an unprecedented ability to edit the human genome — with immense promise and risk
- → Gene-environment interaction (not genes alone) determines most complex traits
- → Our growing genetic power demands proportional ethical seriousness

A History Both Scientific and Personal
Siddhartha Mukherjee is an oncologist and Pulitzer Prize-winning author (The Emperor of All Maladies) whose family includes multiple members with schizophrenia and bipolar disorder. His investigation of the gene is simultaneously a scientific and personal history: he wants to understand the science of heredity partly because he wants to understand his own family’s story.
This dual structure — rigorously scientific and deeply personal — gives The Gene an emotional weight that most science histories lack. Mukherjee’s interest in genetics is not abstract; it is an attempt to understand the biological forces that shaped people he loves, and that may shape his own future.
From Mendel to CRISPR
The book’s historical arc spans from Gregor Mendel’s meticulous pea experiments in an Augustinian monastery in 1856 to the CRISPR-Cas9 gene-editing revolution of the 2010s. In between, Mukherjee covers the discovery of DNA’s structure by Watson and Crick (and the largely uncredited Rosalind Franklin), the development of genetic sequencing, the Human Genome Project, and the emerging science of epigenetics.
The history of genetics is not a triumphalist narrative. Mukherjee is unflinching about the devastating chapter of eugenics — the scientifically dressed ideology of genetic improvement that provided intellectual cover for forced sterilisations and, ultimately, the Holocaust. The gene’s history is inseparable from this horror, and Mukherjee insists on remembering it as genetic power rapidly expands.
The CRISPR Revolution
The book’s final sections on CRISPR are among the clearest and most ethically serious accounts of gene editing available for general readers. CRISPR-Cas9 — discovered and developed through a series of brilliant collaborations involving researchers across several countries — allows precise, targeted editing of any DNA sequence in any cell. Its implications for medicine, agriculture, and eventually human germline editing are genuinely unprecedented.
Mukherjee approaches these implications with appropriate seriousness. The question of whether to edit heritable human genetic variants — to eliminate disease predispositions in future generations — is one the book explores carefully without pretending to resolve.
Final Verdict
The Gene is a masterwork of science writing — comprehensive, precise, personal, and morally serious. Required reading for anyone who wants to understand the biology of inheritance and the ethical landscape of the genomic era.
Our rating: 4.6/5 — One of the best science books of the decade. The intersection of personal and scientific history is handled with extraordinary skill.
