Solution (By Examveda Team)

The term genotype and phenotype were coined by physiologist Wilhelm Johannsen in 1911.
The genotype-phenotype distinction is drawn in genetics. "Genotype" is an organism's full hereditary information. "Phenotype" is an organism's actual observed properties, such as morphology, development, or behavior.
This distinction is fundamental in the study of the inheritance of traits and their evolution.
