Genetics

How traits are inherited, expressed, and sometimes altered.

Content last reviewed: August 2026

Genetics studies how genes work, how traits are inherited, how mutations arise, and how genetic information can be read, edited, or applied, spanning classical genetics, molecular biology, and increasingly genomics and bioinformatics. It builds on a general biology and chemistry foundation.

Lab courses cover techniques like DNA sequencing, PCR, and gene editing concepts, and many programs incorporate bioinformatics tools for analyzing large genetic datasets, reflecting how much the field now depends on computational analysis.

Typical courses you might take

  • General Biology & Chemistry
  • Genetics
