Chapter 19/20 test on Friday June 7th

Study Guide

Bring a calculator, pen and highlighter.

19.1 Hardy-Weinberg Principle

• Understand the terms population, genes, allele, gene pool, genotype frequency, phenotype frequency, allele frequency
• Summarize the five conditions of the Hardy-Weinberg principle
• Use the Hardy-Weinberg equations to calculate allele and genotype frequency of a population

19.2 The Causes of Gene Pool Change

• List and describe what causes a change in the gene pool (mutation, gene flow, non-random mating, genetic drift, the founder effect, the bottleneck effect, natural selection)

20.1 Population Growth

• Define density and distribution
• Calculate population density, population growth rate and per capita growth rate
• Explain biotic potential, carrying capacity
• Compare the characteristics of populations with r-selected and K-selected life strategies, name examples of organism

20.2 Interactions in Ecological Communities

• Describe the difference between intraspecific and interspecific competition
• Describe the relationship between predators and prey (analyze predator and prey population cycle-graph)
• Explain how producers defend themselves against consumers (cryptic coloration-protective coloration, batesian and muellerian mimicry)
• Define symbiosis and explain the difference between mutualism, commensalism and parasitism
• Explain what is succession and distinguish between primary and secondary succession, pioneer and climax community
