Question

The presence of continuous phenotypic variation in an F${}_1$ generation, suggests that a character is inherited by

• A. Epistasis
• B. Recombination
• C. Gene linkage
• D. Polygenic inheritance

Answer 1

The correct option is D Polygenic inheritance

When one character is controlled by two or more genes, the condition is called polygenic inheritance e.g. height, skin color, eye color & weight. It differs from Mendelian inheritance where traits are determined by a single gene.

So, the correct answer is "Polygenic inheritance".
