What do scientists study in genetics?

• A. Energy production in cells
• B. How traits are inherited and expressed
• C. The study of ecosystems
• D. The laws of motion

Answer: (B)

Genetics studies how information in genes is passed from parents to offspring and how that information shapes the traits we see. It focuses on DNA, genes, and alleles, and on how they segregate and recombine during reproduction to produce genotypes that determine phenotypes. This includes learning why some traits appear in every generation (dominant traits), why others skip generations (recessive traits), how sex-linked traits behave, and how multiple genes can influence a single feature (polygenic inheritance). It also covers how environment can influence gene expression and how mutations introduce new variation. In short, genetics is about the inheritance and expression of traits, while other fields study different biological questions like how cells generate energy, how organisms interact in ecosystems, or how physical forces govern motion.
