Genetics and Heredity

In Genetics and Heredity, students will discover how the information contained within DNA is expressed as observable traits.  They will learn about gene alleles and how dominant and recessive alleles operate. Students will understand the difference between genotype and phenotype as they investigate what traits they and their family members express.  The steps of meiosis are reviewed, and students will discover how this special form of cell division leads to genetic diversity in offspring. Students will learn about Mendelian inheritance and how to use Punnett Squares to predict the outcome of monohybrid and dihybrid crosses.  Additionally, students will learn about patterns of non-Mendelian inheritance including sex-linked traits, the inheritance of mitochondrial DNA, incomplete dominance, codominance, and polygenic traits. Throughout the course, students will be exposed to many real-life examples of genetics in action as they learn about the genetics of calico cats, human blood types, how hemophilia was spread throughout the royal houses of Europe, and much more.  Periodic quizzes will test students’ understanding throughout the course. Students will solidify their understanding as they use Punnett Squares to predict the outcomes of different genetic crosses. Students will also create their own family pedigree. Instructions for several optional lab experiments are also included.  Enrolled students have access to the course materials for one year (366 days).

DNA—deoxyribonucleic acid—is an essential biological molecule found in every living thing on the planet.  Most people understand that DNA contains the information necessary to make living things and that it is passed down from parents to offspring.  In my first course on DNA (DNA basics, Gene Expression, and DNA mutations), students learned how DNA genes are expressed within the cell through the processes of transcription and translation.  They also learned how DNA mutations can directly lead to diseases such as cancer, Sickle Cell Anemia, Cystic Fibrosis, and Tay-Sachs disease by producing faulty proteins. But how does DNA—found inside each of our cells—manifest itself as observable traits?  How does our DNA control the color of our eyes, how tall we are, or if we are right or left handed?  And if DNA is passed down from parent to child, how can two parents with brown hair and brown eyes  have a child with red hair and blue eyes?  Is it possible for or two parents with normal vision to  have a child who is color-blind?  Do you know how to predict the outcome of such genetic crosses?

    Ever wondered how a child with two brown-eyed parents can end up with blue eyes? This course answers this and so much more! “Genetics and Heredity” provides you with tools to map the genetics of your family in so many ways, cementing the concepts covered and helping students bring the concepts off the screen and relate it to their lives.
