Polygenic Inheritance Flashcards

All 3 cards in this deck

What is polygenic inheritance?

When a characteristic is controlled by several genes working together, rather than by a single gene.

Are most phenotypic features controlled by one gene or by several genes?

Several genes — most features are polygenic.

True or false? Human height is controlled by a single gene.

False. Height is polygenic — it is controlled by many genes (and also affected by the environment).
