Final Answer:
Sex-influenced characteristics are encoded by autosomal genes that express more readily in one sex, exhibiting varying levels in males and females. In contrast, sex-limited characteristics are encoded by autosomal genes expressed exclusively in one sex, completely absent in the other, contributing to distinctive features specific to either males or females.
Step-by-step explanation:
Sex-influenced characteristics are encoded by autosomal genes that are expressed more readily in one sex but can be present in both sexes. These traits may exhibit different levels of expression based on hormonal influences, showcasing variations between males and females.
On the other hand, sex-limited characteristics are encoded by autosomal genes expressed exclusively in one sex, and they remain absent in the other. These traits are often associated with the reproductive or anatomical differences between males and females. Understanding the distinction between sex-influenced and sex-limited characteristics is crucial in unraveling the complexities of genetic expression and the interplay between genetics and sexual dimorphism.
