The answer is; obesity can cause diabetes
It is believed that obesity caused stress on the body cells making them produce cytokines, proinflammatory markers that make them resistant to insulin. Obesity can also impair the beta-islets cells of the liver that produce insulin. All these make the body's response to glucose levels unregulated causing diabetes.
1 one is correct.....he never think about linkage......later after chromosome mapping it was found that Mendel was lucky that they don't show much linkage !
