How does a human disorder often relate to another disorder in mammals?

• A. It has a viral basis
• B. It resembles a genetic disorder
• C. It is caused by environmental factors
• D. It involves a chromosomal mutation

Answer: (B)

The relationship between a human disorder and another disorder in mammals often lies in the resemblance to a genetic disorder. Many human diseases have homologous counterparts in other mammals due to shared evolutionary traits and similar biological processes. For example, certain genetic mutations that cause disorders in humans may lead to analogous conditions in other mammals, reflecting conserved pathways or mechanisms that underlie those disorders. This resemblance helps scientists to study human diseases using animal models, which can reveal insights into the genetic basis of diseases, potential treatment options, and biological functions. These similarities can be critical in understanding the etiology of human disorders, allowing researchers to explore genetic components within a broader biological context. In contrast, while other factors such as environmental influences and chromosomal mutations are certainly relevant in the study of diseases, they do not specifically address the structural and functional parallels that often exist between human disorders and those seen in other mammals. Furthermore, a viral basis may explain certain diseases but does not establish a direct relational framework to another disorder across species, making genetic resemblance the more fitting connection.
