Students analyze gels to determine parentage in this instructional activity about scientific evidence, investigation, and DNA concepts. The instructional activity includes a pre-activity worksheet, a final individual assessment, and...

Students examine the phenotypic variation within a natural population of a single species. They collect data on the species and analyze the data using statistical/spreadsheet software. Students interpret their results and present their...

Students use this laboratory exercise as a growth medium that contains the macronutrient and micronutrient needs of plants. They observe the effects of different hormones on tissue cultures and must use variations of the basic growth...

Young scholars describe some aspects of known genetic defects on the human neurological condition. They participate in a variety of exercises including drawings, games, and analogies.

Student groups use lima beans to represent dicots and corn to represent monocots, soak the seeds, and separate the embryos from the cotyledons. They then place the seeds in Petri dishes in agar and observe for at least one week recording...

Studnets compare how two elephant seal populations fare during successive generations. They participate in a simulation using a card game to look at the differences in two populations, one that is protected from mortality by human...

Students read a story about the life of Russian plant breeder Nikolai I and Vavilov and the national seed bank he established. They research the Irish Potato Famine of the late 1840s and identify the cause for this famine and make...

In this biology worksheet, 9th graders identify and locate various vocabulary terms related to the study of genes. There are 18 biology terms located in the word search.

Tenth graders work on a project about cellular biology and genetics. In this biology lesson, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia presentation and...

Students identify the different kinds of blood. In this biology lesson plan, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

Students explore evolutionary concepts in cartoons and lab activities. They describe and explain evolutionary concepts featured in a cartoon and participate in laboratory activities.

Resource provides a definition of "genotype" and a detailed audio explanation of the term, and links to related terms.

This site talks about the differences between genotype and phenotype. It offers examples, and tells how a genotype determines a phenotype.

In this informative site, you will find the definition of genotype and phenotype, an explanation of the relationship between genotype and phenotype, an example of a genetic trait, an explanation of the flow of information from DNA to...

The definition and links to supplemental sites are avaialbe here. A variety of languages are also offered for the definition.

This is a group of Mendelian Genetics exercises that are designed to show the evolution of a trait within a population. The site covers instruction in calculating genotypic and allelic frequencies, determining dominance, the...

Students learn about patterns of inheritance including genotype and phenotype, and then learn about the inheritance of autosomal dominant and recessive and sex-linked genetic disorders.

Do you know the difference between population genetics and quantitative genetics? This webpage examines both population genetics which concentrates on frequencies of alleles and genotypes and quantitative genetics which deals with the...

Resource provides a discussion of Mendel's law of segregation with a focus on genotype, phenotype, alleles, heterozygous/homozygous, and 2 x 2 Punnett squares.

These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. This section has an advanced discussion of determining allele and genotype frequencies using the Hardy-Weinberg ratio.

Using chromosome and gene models, learners play the roles of two parents in this genetics simulation. The object is to create four offspring and determine their genotypes and phenotypes, and determine the probability of having offspring...
