Description: Every human carries two remarkable genetic threads: one passed only from mother to child, the other only from father to son. This book traces the parallel stories of mitochondrial DNA and the Y chromosome, exploring their unique architectures, mutation patterns, and the molecular clocks that let researchers reconstruct deep ancestry. Through haplogroups, coalescence theory, and the challenges of selection and recombination, readers will see how these asymmetric inheritance systems illuminate human migration and evolution. A rigorous yet accessible guide to how two single-parent lineages, read together, map the journey of our species.
