Study Notes

Human Genetics Course Overview and Activities

The course covers five units: Introduction to Human Genetics, Genetics and Disease, Epigenetics, Reproductive Technologies, and Ethical Issues in Genetics.
The course emphasizes building trust, practicing empathy, and improving communication skills.
Assignments include a unit case study/review worth 15% of the final grade, a unit exam worth 10% of the final grade, an end-of-semester seminar worth 25% of the final grade, and a final exam worth 20% of the final grade.
Open Education Resources are used in the course, and students are taught how to properly cite their sources in MLA format.
Class activities include mindful listening exercises, pair/shares, and active reading of articles related to genetics and ethics.
Topics covered in the course include stem cells, inheritance of traits, and genetic testing.
The course explores the ethical implications of genetic engineering and reproductive technologies.
Eye color is determined by a single gene on chromosome 15, while hair color and height are influenced by multiple genes.
Holandric inheritance refers to traits that are only passed down from father to son, while maternal inheritance refers to traits that are only passed down from mother to offspring.
The course encourages critical thinking and discussion on controversial topics such as therapeutic cloning and genetic testing.
Students are expected to participate, arrive on time, put away cell phones, and submit work on time.
The course emphasizes taking responsibility for one's actions and not waiting until the last minute to complete assignments or prepare for exams.Introduction to Human Genetics: Inheritance, Chromosomes, and Traits
Individuals deficient in 5-alpha-reductase have internal genitalia due to external genitalia not developing.
The X chromosome has over 1,500 genes, while the Y chromosome has only 231 protein-encoding genes.
The SRY sex determining gene is located on the Y chromosome.
Maternal inheritance comes from the mother, while holandric inheritance comes from the father.
X-linked recessive traits rarely affect females due to having two copies of the X chromosome.
X-linked dominant traits are more severe in males, while females are affected less frequently.
Sex-limited traits only affect structures or functions present in one gender, such as pre-eclampsia.
Sex-influenced traits have alleles that are dominant in one gender and recessive in the other, such as male pattern baldness.
Mitochondria have their own DNA and are inherited solely from the mother.
Sperm cells do not contribute mitochondria, and many mitochondrial mutations do not survive.
Heteroplasmy refers to mutations present in some mitochondrial DNA but not all.
The exam for this unit will cover historical and modern approaches in human genetics, stem cells, genetic information maintenance, protein product specification, and inheritance patterns.
