Summary Introduction
To analyses:
Why is it easier to describe heredity using single-gene trait?
Introduction:
Inheritance occurs as a result of passing on of alleles of various from traits from parents to offspring. Single-gene traits are those traits whose inheritance can be determined using a single gene.
