In a 21st century globally-competitive society, agriculture is rapidly progressing and incorporating more innovative STEM practices (Science, Technology, Engineering and Mathematics). A number of agriculture advances incorporate genetics, which is an important unit in seventh-grade science. The lesson exposes students to a real-life application of genetics and technology to improve agriculture production and profit. The lesson specifically addresses bioengineering, biotechnology and selective breeding. Students use the technique of selective breeding in a class competition to make the best and most profitable grapes to sell to local industries. In doing so, they will learn about progressive agriculture science and technology, while covering the seventh-grade science genetics standards.

This course reviews the key genomic technologies and computational approaches that are driving advances in prognostics, diagnostics, and treatment. Throughout the semester, emphasis will return to issues surrounding the context of genomics in medicine including: what does a physician need to know? what sorts of questions will s/he likely encounter from patients? how should s/he respond? Lecturers will guide the student through real world patient-doctor interactions. Outcome considerations and socioeconomic implications of personalized medicine are also discussed. The first part of the course introduces key basic concepts of molecular biology, computational biology, and genomics. Continuing in the informatics applications portion of the course, lecturers begin each lecture block with a scenario, in order to set the stage and engage the student by showing: why is this important to know? how will the information presented be brought to bear on medical practice? The final section presents the ethical, legal, and social issues surrounding genomic medicine. A vision of how genomic medicine relates to preventative care and public health is presented in a discussion forum with the students where the following questions are explored: what is your level of preparedness now? what challenges must be met by the healthcare industry to get to where it needs to be?

"One underexplored factor that affects the food industry is the gut microbiome of animals raised for consumption. Gut microbes play big roles in how animals break down food and absorb nutrients and thus how animals grow and develop. A new study explored the links between gut microbial communities, fish feed conversion, and fish genetics in the domestic Atlantic salmon. While researchers observed weak associations between host genetics and microbial composition, they did identify bacteria linked to carbon metabolism in fat tissue and feed efficiency, as well as weight gain. The findings highlight some of the roles played by gut microbes in the metabolism of Atlantic salmon, which could affect how the fish are raised for consumption..."

"Feed efficiency is an important economic and environmental parameter in raising swine. It captures how effectively livestock feed is turned into food products for humans. Increasing a pig’s feed efficiency can reduce a farm’s costs and energy use. A new study shows that one factor that could affect pigs’ feed efficiency is their gut microbiome. Feed intake and body weight measurements showed significant differences in feed efficiency among three pig breeds: Duroc, Landrace, and Large White, while genetic analyses of their gut microbiomes revealed differences in their microbial makeup. Association analyses between these datasets indicated a positive association between 4 types of bacteria and feed efficiency. This link could help both scientists and farmers understand how intestinal microbes influence animal traits crucial to production. such as those related to fatness. And it could offer a valuable new way to influence the feed efficiency of pigs..."

Help Me Understand Genetics presents basic information about genetics in clear language and provides links to online resources.
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.
How can we Design Cattle to Better Meet Human Needs?
In this high school Storyline unit on genetics and heredity, students are introduced to ‘SuperCows’. As they explore the vast variety of cattle breeds, students discover that cattle are specialized for different purposes and while similar, the ‘SuperCows’ are clearly unique. Students wonder what caused this diversity and specificity which leads to investigations about the role of inheritance, DNA and proteins.

"The honey bee gut microbiome has a critical influence on bee health and is transmitted among members of a colony through social interactions. The bee microbiome is made up of a core set of bacterial groups that show high diversity among individuals at the strain level. While this variation has been shown to be clearly associated with numerous environmental factors, bee genetics may also play an important role. Researchers recently used DNA sequencing techniques to better understand how bee genetics affect gut microbiome structure. The team examined the genomes of four subspecies of lab-reared honey bees with those of their associated microbiomes. They noted that the abundance of most core gut microbiota members was influenced by host subspecies and also found a clear link between a Bifidobacterium strain in the gut and brain neurotransmitter and gene expression patterns..."

Students are introduced to the latest imaging methods used to visualize molecular structures and the method of electrophoresis that is used to identify and compare genetic code (DNA). Students should already have basic knowledge of genetics, DNA (DNA structure, nucleotide bases), proteins and enzymes. The lesson begins with a discussion to motivate the need for imaging techniques and DNA analysis, which prepares students to participate in the associated two-part activity: 1) students each choose an imaging method to research (from a provided list of molecular imaging methods), 2) they research basic information about electrophoresis.
