Linked genes do not follow the Law of Independent Assortment because they are inherited together unless crossing over occurs.
Ref: NCERT Class 12 Biology Chapter 4: Principles of Inheritance and Variation Mendel's Laws - Dominance Segregation Independent Assortment
Linkage occurs when genes located close together on the same chromosome tend to be inherited together.
Ref: NCERT Class 12 Biology Chapter 4: Principles of Inheritance and Variation Mendel's Laws - Dominance Segregation Independent Assortment
Mendel chose pea plants because they have a short life cycle and well-defined contrasting traits.
