Question

What did Nils Herman Nilsson-Ehle develop through his wheat kernel colour experiments?

Options

• The 'multiple factor' theory of polygenic inheritance

• The law of independent assortment

• The law of segregation

• The theory of incomplete dominance

Answer 1

Nils Herman Nilsson-Ehle developed the 'multiple factor' theory through his classic experiments on wheat kernel colour. His work demonstrated that a single quantitative trait (kernel colour) could be controlled by multiple independent genes, each contributing additively to the phenotype. This theory forms the foundation for understanding polygenic inheritance in both plants and animals.
