Population Genetics and Evolution

Start with population genetics

Begin with the mind map Population genetics; the Hardy-Weinberg principle. It introduces the gene pool as the sum of the alleles in a population and also covers allele frequency. Use it to get familiar with the terms before moving to the flashcard deck Population genetics - genetics, which asks why genes are studied in populations and introduces gene frequency and the gene pool.

For more practice with terminology, try the flashcards in Chapter 25: Population Genetics. They cover genetic drift, genetic rescue, gene pools and frequencies, including calculating genotypic frequency. Go through the cards once, then return to any terms you want to study again.

Move from variation to evolution

The variation mind map listed near the top of the page considers whether variation in a characteristic is genetic, environmental or both. The flashcards in Genetics and Evolution cover terms such as locus, genotype, dominance, penetrance and expressivity. Together, these resources give you different ways to study the vocabulary that appears across the topic.

The population genetics flashcards also ask about genetic drift and how it compares with natural selection. You can follow these with a genetic drift mind map to explore the topic in another format.

Combine a quiz with a map

Try Inheritance, Variation and Evolution after looking at a map or flashcard deck. The quiz includes questions on asexual reproduction, chromosomes and natural selection. Use the questions to identify terms you want to look at again, then return to a map or deck that covers them.

Population Genetics and Evolution is part of the Genetics and Inheritance unit in Biology and natural sciences. The inheritance and variation resources on this page provide ways to connect population genetics with the rest of that unit. Choose a map and a quiz to use together as you study.
