Mendelian inheritance in cannabis (the simple version)

Cannabis is a flowering plant, and like every flowering plant, it inherits its traits the same way Gregor Mendel's peas did. You don't need a biology degree to use this — you just need three ideas.

The three ideas

• Every trait is controlled by a pair of genes — one from mom, one from dad.
• Some versions of a gene are dominant. The dominant one wins when both are present.
• When you cross two pure-breeding parents, the first generation (F1) looks the same. When you cross two F1 plants together, the F2 generation splits.
