The Blueprint (Genes and Proteins)
Key Idea
Why do traits get passed down?
Cells contain genes, which are instructions for building protein molecules.

The Blueprint (Genes and Proteins)
Why do traits get passed down?
Cells contain genes, which are instructions for building protein molecules.
Section 2
Inheritance
Organisms do not build their genes from scratch; they inherit them from their parents during reproduction.
This is why the survival of parents matters. If only the high-poison newts survive today, they pass their "high-poison genes" to the babies of tomorrow. The traits of the future population are determined by who reproduces today.
