Question

What are polygenic traits?

(a) Traits controlled by a single gene

(b) Traits not controlled by any genes

(c) Traits controlled by two genes

(d) Traits controlled by three or more genes

I have been asked this question in examination.

Question is taken from Polygenic Inheritance in chapter Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Correct choice is (d) Traits controlled by three or more genes

For explanation I would say: Traits are the feature of a character by which we can distinguish organisms. Traits which are generally controlled by three or more genes are known as polygenic traits.
