DoubleHelix specializes in explaining how genetic information is stored in DNA and transmitted through reproduction, creating both similarities and differences between parents and offspring. It reveals how genetic variation provides the raw material for evolution.

Drawing from classical genetics and molecular biology, DoubleHelix explains how genes control traits, how mutations create variation, and how genetic testing reveals inheritance patterns. It connects genetic principles to family histories and medical decisions.

Readers develop understanding of how inheritance works and how genetic variation creates both family resemblances and individual uniqueness. Each article demystifies genetic concepts and their relevance to personal and family health.
