Biology II Advanced Survey · Evolutionary Mechanisms
Virginia SOL BIOII.5
Virginia SOL BIOII.5 is part of the Evolutionary Mechanisms strand in Biology II Advanced Survey (Science). Under this Standards of Learning objective, students investigate how evolutionary mechanisms affect the genetic makeup of populations over time. Below is what BIOII.5 covers in plain language, the specific skills it is assessed on, the key concepts to review, and how to practice BIOII.5 for the Virginia SOL test.
What SOL BIOII.5 means
Investigate how evolutionary mechanisms affect the genetic makeup of populations over time.
Skills you’ll practice for BIOII.5
- Make, support, and evaluate a claim about the effect of selective pressures on species evolution.
- Explain the effect of changing environmental conditions on the allele frequencies in a population.
- Develop and use a model to explain how evolutionary factors (gene flow, genetic drift, mutation, non-random mating, and natural selection) change allele frequencies over time.
- Develop and use a model to explain the effects of inbreeding and genetic drift in small, isolated populations.
- Make, support, and evaluate a claim about how speciation occurs.
- Make, support, and evaluate a claim about how evolution happens at the population level.
