Question 1

Correct Answer:

Verified

Darwin's theory lacked a mechanism for the inheritance of desirable characteristics.Gregor Mendel discovered the principles of inheritance, i.e., the basis for understanding how traits are transmitted from parent to offspring.Mendel's discovery that traits are passed as discrete units (genes) laid the foundation for our understanding of chromosomes and of population genetics.
