<span>Biological scientists are research scientists who examine how living organisms relate to the environment. They can specialize in any number of plant, animal or environmental studies. Biological scientists most often have earned a master's or doctoral degree in their specialization; such degrees offer the opportunity to develop research while finishing their education. Some low-level positions related to biological science are available to those holding baccalaureate degrees.</span>
        
                    
             
        
        
        
Answer: D) Polygenic
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
