All human infants are lactose tolerant, yet some adults are lactose intolerant—why is that? Individuals discover the process of gene mutation through a study of the lactase gene (LCT). They understand the geographic connections,...

In this genetics worksheet, students complete 3 short answer, a word puzzle, and 7 word games about genetic traits.

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

In this evolution and genes worksheet, students answer 10 multiple choice questions related to genetics, DNA, polygenic traits and heredity.

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

How do genetics gurus know so much about gene expression? See traits materialize before your very eyes using a presentation with embedded simulations. Science scholars develop an understanding of the techniques used to follow the work of...

DNA carries the codes for creating just the right protein. A well-designed activity leads pupils through the process from start to finish and everywhere in between. Guiding questions with supporting video help scholars understand the...

Can you name a type of reproduction that produces no variation in the offspring? The multimedia lesson covers both sexual and asexual reproduction through videos and discussions. It includes topics such as genetic modification, meiosis,...

Explore the complexities of reproductive genetic testing respectfully in the learning space. Scientists read articles, view a slideshow, and complete a do-now about genetic technologies. A fishbowl activity allows scholars to discuss the...

In this RNA and gene expression worksheet, students match the letter of the description that best matches the term as it relates to gene expression. Students also answer questions as it relates to the process of transcription and...

In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...

Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and...

Designed to accompany the 13-minute video The Making of the Fittest: The Birth and Death of Genes, this handout serves as both a viewing guide during the video and an analysis of how the adaptations of the icefish might help treat...

Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

What's the future of biotechnology? Explore a hot topic in the fourth and final unit in a series of Biotechnology lessons. Learners develop an understanding of the many issues in bioethics, then create an argument for or against the role...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Two individuals share 99.9 percent of their genetic codes, yet diversity is observed everywhere. Young scientists learn about diversity through hands-on activities and an experiment. They apply the concepts of independent assortment and...

Students research the population of Bengal tigers and their existence as either dominant or recessive. They explore the presence of fur on these tigers and its lethal combinations. Determinating the effect of random mating in a...

A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...

How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...
