You probably know that it is DNA that carries the genetic instructions for building YOU as well as every other living thing on the planet.
But how does the DNA inside each of our cells govern our genetic traits: eye or hair color, whether we are right- or left-handed, or whether or not we like the taste of cilantro?
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 two parents with normal vision to have a child who is color-blind?
In this course, students will learn how cellular DNA is expressed as observable traits. Students will learn:
- how DNA is packaged into homologous chromosomes
- that many genes come in different “flavors” called alleles
- how some alleles are dominant and others are recessive
- the important distinction between genotype and phenotype
- the difference between homozygous, heterozygous, and hemizygous genotypes
- the work done by Gregor Mendel and the principles of Mendelian Inheritance
- the laws of segregation and independent assortment
- all about meiosis, crossing over, gametogenesis, and the importance of genetic diversity
- how to use Punnett Squares to predict the outcome of monohybrid and dihybrid crosses
- the distinction between probability and real life when it comes to Punnett Squares
- patterns of non-Mendelian inheritance including sex-linked traits, codominance, incomplete dominance, the inheritance of mitochondrial DNA, and polygenic traits
- how to construct (and read) a pedigree
- the genetics of human blood types
- how nondisjunction occurs
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, cystic fibrosis, 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. Instructions for several optional lab experiments and hands-on activities are also included.
I really enjoyed the Genetics and Heredity course! I feel taking the first course would be ideal to already know some of the info for this course. The learning experience is super fun and informative! Can’t wait for the next!-Kirin G.
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.-Stacy A.
