Human Genetics Quiz

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.
