"Easter" Egg Genetics
Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...
Curated OER
Biology-Genetics
High schoolers predict the probable mode of inheritance from a pedigree diagram showing phenotypes. They study the genetic basis for Mendel's laws of segregation and independent assortment. They give a Power Point slide show...
Curated OER
Frankenfish
Students learn the difference between a genotype and a phenotype. They demonstrate that recombination of gametes (coins) will result in the formation of unique individuals.
Curated OER
Science Lesson for Grade 12
Twelfth graders perform dihybrid crosses and calculate phenotype and genotype ratios. In this series of science lessons, 12th graders explain the process of anodizing aluminum. They research on the benefits and harm caused by resonance...

Phenotypic and Genotypic Changes in Bacteria
Students investigate a rapid method to render the bacterium Escherichia coli "competent" to uptake plasmid DNA. They demonstrate the phenotypic changes associated with transformation. They perform a cell resuspension from the...

PHENOTYPIC AND GENOTYPIC CHANGES IN BACTERIA
Students use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a cell...

Punnett Squares with Piebald Deer
Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...
Curated OER
Inheritance in Maize
Learners use mutant corn ears to investigate inheritance patterns. In this inheritance lesson plan, students count the number of corn kernels of each phenotype in mutant and wild type ears of corn. Learners calculate the ratio of...
Curated OER
The Spanish Omelet
Students use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs. environmental...
Curated OER
A Sputtering Image
Students explain the role of genes in heredity. In this biology activity, students predict the offspring's genotypes and phenotypes using the Punnett Square. They compute the probability of genotypes and phenotypes.
Curated OER
My Family And Me
Students create a family pedigree, relate the laws of inheritance to a family pedigree, and determine certain phenotypes and corresponding genotypes of members in their family.

Biology Honors Final Project
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...

Parental Genes
Eighth graders explore how different organisms pass their traits to their offspring. In this life science lesson plan, 8th graders differentiate recessive and dominant alleles. They predict the phenotype based on the genotype of an...
Curated OER
Genetic Phenotypes of the Super Heros
Students learn that genetic differences exist in all of us. That diversity is what makes us unique as individuals. Phenotypes are the physical characteristics that we develop from our genotype (our genetic makeup). Both the environment...
