who proposed the theory of inheritance of acquired character
Inheritance of acquired characteristics The inheritance of acquired characteristics was proposed in ancient times by Hippocrates and Aristotle, and was commonly accepted near to Lamarck's time; Erasmus Darwin had described it in his Zoonomia, 1794. The historian of science Conway Zirkle wrote that:
Mendelian inheritance A Mendelian trait is one that is controlled by a single locus in an inheritance pattern. In such cases, a mutation in a single gene can cause a disease that is inherited according to Mendel's laws. Examples include sickle-cell anemia, Tay-Sachs disease, cystic fibrosis and xeroderma pigmentosa. A disease controlled by a single gene contrasts with a multi-factorial disease, like arthritis, which is affected by several loci (and the environment) as well as those diseases inherited in a non-Mendelian fashion.[citation needed]
