A: The terms genotype and phenotype were invented by Wilhelm Johanssen.
Q: What is the purpose of the genotype-phenotype distinction?
A: The genotype-phenotype distinction distinguishes between inherited and environmentally produced variation.
Q: Why was the genotype-phenotype distinction not a new concept?
A: The concept of inherited versus environmentally produced variation had been previously discussed by Francis Galton, among others.
Q: Are all aspects of the phenotype determined by heredity?
