Gregor Mendel (1865-1866) - ANSWER- Using pea plants he observed what he called the Laws of Heredity: 1. Law of Segregation - there is one gene per sex cell, so we have to genes, one from each parent. 2. Law of Independent Assortment - traits are inherited independently, found to be untrue for all (linkage). 3. Law of Dominance - there are recessive and dominant traits, not all of them. Thomas Morgan (1910) - ANSWER- Chromosome Theory of Inheritance: 1. Sex chromosomes 2. Chromosome pair...

How did evidence from the study of metabolic defects contribute to the fundamental relationship between genes and proteins? - ANSWER -Garrod suggested that genes dictate phenotypes through enzymes that catalyze specific chemical reactions -Symptoms of an inherited disease reflected inability to synthesize a certain enzyme. -Linking genes to enzymes required understanding that cells synthesize and degrade molecules in a series of steps called the metabolic pathway. Describe the experiment by...
