Question

life scientists are trying to identify the genes involved in polygenic traits, in part, to make a clinical approach called \personalized medicine\ possible. based on the information provided, which statement best summarizes the connection between polygenic traits and interest in personalized medicine?
most diseases have such a simple genetic and environmental basis that a \one size fits all\ approach, with standardized drugs and dosages, is appropriate.
better treatment plans and outcomes are possible when physicians know which alleles a person has of genes involved in disease.
medical issues are a highly personal matter, and the confidentiality of any information shared between provider and patient is of the utmost importance.
finding the genes involved in important polygenic traits has been extremely difficult, however. to understand why, lets consider how researchers go about finding the genes responsible for human illnesses that are caused

Explanation:

The question is about summarizing the connection between polygenic traits and personalized medicine. The key points are that polygenic traits involve multiple genes, and personalized medicine aims to use genetic information (like specific genotypes) to create better - tailored treatment plans. The text mentions that a "one - size - fits - all" approach (with standardized drugs and dosages) is not ideal as most diseases (polygenic) have complex genetic bases. Personalized medicine considers the unique genetic makeup (including which alleles a person has) to improve treatment outcomes.

Answer:

Most diseases have a polygenic basis (involve multiple genes). A “one - size - fits - all” approach (standardized drugs and dosages) is not appropriate. Personalized medicine uses genetic information (such as specific genotypes) to make better treatment plans. It considers the connection between polygenic traits (involving multiple genes) and an individual's unique genetic makeup (which alleles a person has) to improve treatment outcomes, rather than a one - size - fits - all method.
