Monogenic Traits
Monogenic traits are characteristics that are controlled by a single gene. An example of a monogenic trait is the cleft chin, which is determined by the alleles of one specific gene inherited from each parent.

Monogenic Traits
A researcher observes that a child has the same distinctive eye color as their biological mother. The researcher also notes that the child has the same favorite food—pizza—as their mother. Based on the definition of a trait as a characteristic at least partially controlled by genes, which statement provides the best analysis of these observations?
A researcher is studying why some individuals are consistently more outgoing and sociable than others at social gatherings. The researcher hypothesizes that this tendency is not just a learned habit, but may be partially inherited. Which of the following statements best justifies investigating this social tendency as a potential trait?

Cleft Chin as an Example of a Monogenic Trait
A botanist is studying a plant species where flower color is an inherited characteristic. Through extensive cross-breeding trials, she consistently observes that the flower color (either red or white) is determined exclusively by the combination of two alleles at a single, specific location on a chromosome. Based on this evidence, which of the following is the most accurate classification for the flower color characteristic in this plant?
A researcher is studying a newly discovered species of insect. They observe that some insects have spotted wings while others have solid-colored wings. After conducting several generations of breeding trials, they conclude that the wing pattern is determined by the alleles of one specific gene. Based on this finding, how should the researcher classify the wing pattern trait?
