How often do you find a science worksheet that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology leaners...

Students study genetic traits using popsicle sticks as chromosomes. In this biology instructional activity, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

If Parseltongue is a genetic trait, what is the probability a wizard will inherit the ability to speak Parseltongue? Scholars investigate magical and biological genetics with Punnett squares.

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual...

Easy-to-read notes about Mendel's Laws of Heredity make up this collection of slides. In bullet-point style, viewers are exposed to Mendel's pea plant experimentation and the rules he developed that govern genetics. There are no graphics...

Parts of the cell as well as genetic material begin this presentation.  As the slides continue, there are explanations of the main terms used in genetics.  The structure of genetic material, chromosomes, and replication are...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

In this biology worksheet, students use the information given to complete each of the questions. They indicate whether each genotype is heterozygous or homozygous. Students also complete the Punnett square to illustrate the possibilities...

In this genetic worksheet, students will complete 4 fill in the blank questions about selective breeding and determining genotypes. Then students will use a Punnett square to determine the genotype for two different breeding situations.

In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

Students determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.

Hilarious! Use the characters from SpongeBob Square Pants to practice solving genetics problems! Yellow sponge body color is dominant to blue. Square body shape is dominant to round body shape. Did someone switch Mr. Krab's baby...

An interesting PowerPoint which provides the main facts, definitions, and terminology necessary for understanding DNA. It also presents summaries of the processes involved with DNA replication and the application of protein isolation and...

Although the instructions include reading from a specific textbook, the tasks are appropriate for any unit dealing with how genotype frequency changes over time. Junior biologists define five vocabulary terms and then answer five...

Blood types and transfusions are explained in reading passages at the top of the worksheet. A chart of blood type compatibility is also provided. Biology students answer comprehension questions and then exercise critical-thinking skills...

Students predict possible phenotypic and genotypic outcomes for avariety of common plant hybrids. They review and explain the characteristics of dominant and recessive traits and explore Mendelian genetics. Students plot the possible...

Learners solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. In this forensic science lesson, students identify the different blood types. They explain how blood tests work.

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.

In this genetic disorders worksheet, students complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.

In this genetics activity, high schoolers answer a variety of questions about genotypes, phenotypes, genetic inheritance, and traits. They solve for the probability of genotypes and phenotypes of offspring by completing monohybrid and...

In this dihybrid cross worksheet, students complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.

Students investigate how traits are passed from parents to offspring via meiosis and fertilization. They recognize that the combination of alleles forming a gamete is random.
