Question

Quizplus · Accepted Answer

The fundamental principle of modern genetics is the theory of inherited traits passed down through genes from parents to offspring, which is not represented by any of the given options. A) Pangenesis is an old and outdated theory proposing that body parts shed particles called "gemmules," which gather in the reproductive organs and are passed down to offspring, leading to the inheritance of acquired characteristics. B) The inheritance of acquired characteristics posits that traits acquired during an individual's lifetime can be passed down to offspring genetically. This theory has been discredited. C) The blending theory suggested that inherited traits were blended together in offspring, resulting in intermediate or mixed characteristics. This theory is not consistent with observed phenomena, such as distinct recessive traits that can skip a generation before reappearing in offspring.
