Carolina LabSheets

  • Two-Point Linkage with Drosophila In this lab students explore the genetic consequences of gene linkage using an F1 cross of Drosophila. View »
  • Three-Point Linkage with Drosophila In this lab students investigate the effects of gene linkage and crossing-over on the inheritance of three traits of Drosophila. They use the data they collect to construct a linkage map of the gene loci. View »
  • Testing for Segregation of Alleles In this lab, students test corn pollen for evidence of the segregation of alleles. View »
  • Meiosis and Genetics In this lab, students investigate how the events of meiosis relate to Mendelian genetics. View »
  • Lumbriculus: Contraction Rate of the Dorsal Blood Vessel In this introductory physiology lab, students determine the contraction rate of the dorsal blood vessel of the blackworm Lumbriculus. Students then design and conduct an experiment to determine the effect of temperature change or chemical exposure on the contraction rate. View »
  • Investigating a Phenotype In this activity, students investigate a phenotype that is not so conspicuous, and they perform a simple chemical test to reveal the underlying basis of the phenotype. View »
  • Introductory Genetics with Drosophila Use this LabSheet with a variety of our Drosophila cultures and sets for introductory labs covering monohybrid, dihybrid, and sex-linked crosses. View »
  • Introduction to Drosophila: Phenotypes In this lab students compare phenotypes of mutant Drosophila to wild type. The activity is intended as a student’s first experience working with Drosophila. View »
  • Genetics with Drosophila F1 Crosses: Sex-Linkage Drosophila genetics labs without the the need to select virgin female flies for crosses. We ship F1 flies so your students need only to set them up in fresh vials to produce an F2. View »
  • Genetics with Drosophila F1 Crosses Drosophila genetics labs without the the need to select virgin female flies for crosses. We ship F1 flies so your students need only to set them up in fresh vials to produce an F2. View »
  • Gene Interaction with Drosophila How do genes interact in the inheritance of traits? Find out in this intriguing study of the inheritance of eye color in Drosophila. View »
  • Daphnia Heart Rate In this introductory physiology lab, students determine the heart rate of Daphnia magna and then test the effect of changing temperature on the heart rate. View »
  • Animal or Not? In this lab students compare an animal to an animal-like protist, or protozoan. View »
  • Investigating a Lethal Trait In this lab, students investigate a lethal trait, albinism, using corn seedlings. View »
  • Introduction to Phenotypes with Wisconsin Fast Plants® In this lab, students germinate seeds of Wisconsin Fast Plants and examine the plants that grow from them for differences in appearance. This introductory-level activity can be used as a pre-lab to a unit on Mendelian genetics, and assumes that students are familiar with the terms genotype, phenotype, and allele. View »
  • Dealing with Data In this introductory lab, students collect data and then devise methods to organize and display the data to give it more meaning. After brainstorming and evaluating their methodologies, they graph the data and perform a written analysis of their results. View »
  • Linkage Determination with Drosophila In this lab students use the Drosophila stock Curly/Plum; Dichaete/Stubble to determine which chromosome an “unknown” mutation is located upon. They also determine whether the unknown mutation is dominant or recessive, and whether it is autosomal or sex-linked. View »
  • Seedling Genetics (Corn) Students study F2 seedlings to discover how a dwarf phenotype is inherited in corn. They determine that the allele for tall height exhibits complete dominance to the allele for dwarf, that the seedlings are segregating in a ratio of 3 tall to 1 dwarf, and that the parent plant was tall and heterozygous. View »
  • Carolina LabSheets™: Seedling Genetics (Sorghum) Students study F2 seedlings to discover how a color phenotype is inherited in sorghum. They can study a cross involving green and albino plants or, alternatively, a cross involving red and green plants. View »
  • Seedling Genetics (Soybean or Tomato) From a study of either soybean seedlings or tomato seedlings, students determine that the color alleles involved exhibit incomplete dominance, that the seedlings are segregating in a ratio of 1 green:2 yellow-green:1 yellow, and that the parent plant was yellow-green and heterozygous.
