Students work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create models of cells undergoing these changes. In the third lesson, students create Punnett squares, and participate in an interactive lecture on genes, alleles, traite and geno/pheno types. Full Review »

Students discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers representing alleles to determine genotypic and henotypic ratios among offspring. Full Review »

Students view a simple ABO blood system for the introduction of this subject using concrete models of eythrocytes (red blood cells, or RBC's), antigens, and antibodies. They can physically see the antigens that result from certain allele combinations and can move antibodies to determine whether agglutination occurs when two given blood types are mixed. Full Review »

Students observe models of the ABO blood system including erythrocytes, antigens, and antibodies. They investigate the antigens that result from certain allele combinations and move antibodies to determine whether agglutination occurs when two given blood types are mixed. Full Review »

Students explore the principles of incomplete dominance and codominance in genes. They apply genetic previously discussed genetic principles to determine solutions to inheritance problems including multiple alleles, incomplete dominance and codominance. Full Review »

Students review the following vocabulary: Independent assortment, multiple alleles, and polygenic traits. They review their vocabulary by the "quiz, quiz trade" routine. Students work in groups. They are given one set of gene cards for each group. Full Review »

Students study allelic frequencies or genotypic frequencies. They use Hardy-Weinburg's equation to calculate the missing information when given allelic or genotypic frequencies. In addition, they describe the physical characteristics of 6 different species of fish, including a description of the environment in which the fish is best suited. Full Review »

Students listen as the teacher defines key genetic terms: gene, alleles, genotype, phenotype, homozygous, and heterozygous. They discuss the contributions of Gregor Mendel. Students predict the possible genotypes and phenotypes of offspring. Full Review »
