'Lateral gene transfer' diaporamas de présentation

Lesson Overview

Lesson Overview. 17.1 Genes and Variation. THINK ABOUT IT. Darwin developed his theory of evolution without knowing how heritable traits passed from one generation to the next or where heritable variation came from. What would happen when genetics answered questions about how heredity works? .
