Final answer:
Genetics still holds many unanswered questions. Some of these questions include the nature versus nurture debate, the role of epigenetics, and the study of polygenic traits.
Step-by-step explanation:
In the field of genetics, there are several questions that still remain unanswered. One question is about the nature versus nurture debate, which explores how much of an individual's traits are determined by genetics and how much are influenced by environmental factors. Another question is about the role of epigenetics, the study of changes in gene expression that can be inherited without changes to the DNA sequence itself. Finally, there is ongoing research to understand the complexities of polygenic traits, which are traits influenced by multiple genes and the environment.
