Principles of Genetics studies heredity and gene expression — DNA as genetic material, mutation, and inheritance across molecular, cellular, organism, and population levels.
What BIOL 222 covers
Prerequisite: BIOL 105. A study of the principles and mechanisms of heredity and gene expression.
The goal is to articulate the importance of DNA as the genetic material of living organisms and the ways that mutations in DNA can result in disease transmission and species evolution. Topics include patterns of inheritance of genetic material at the molecular, cellular, organism, and population levels.
Typical BIOL 222 assignments
Expect an assignment requiring you to trace an inheritance pattern across multiple levels (molecular through population) and connect it to disease or evolutionary outcomes.
Key topics in BIOL 222
- DNA as genetic material
- Mutation, disease, and evolution
- Inheritance across molecular to population levels
- Mechanisms of heredity and gene expression
Writing tips for BIOL 222
Follow the assignment instructions and rubric line by line
UMGC assignments for BIOL 222 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.
Ground claims in specific biological mechanisms, not general description
BIOL 222 expects claims about a biological process to be explained at the level of the actual mechanism (cellular, molecular, or systemic) — a general or surface-level description, even if directionally correct, usually loses points against the rubric's expectation of mechanistic detail.
Connect the biology to informed, real-world decision-making
UMGC's Biology courses consistently frame content around using scientific reasoning to make informed real-world decisions — an assignment that stays purely descriptive without that decision-making connection is missing a piece the rubric typically wants.

Why students seek help with BIOL 222
Students sometimes address inheritance at only one level (say, molecular) without connecting it across the multiple levels BIOL 222 specifically requires — the rubric typically wants that cross-level connection shown.
