1. Introduction to Genetics

Genetics is the study of genes, DNA, and heredity. Genes are units of heredity that are passed from parents to offspring and determine an organism's traits. DNA, or deoxyribonucleic acid, is the molecule that carries genetic information. Heredity refers to the passing of traits from parents to offspring.

2. Gregor Mendel and the Laws of Inheritance

Gregor Mendel, an Austrian monk, is known as the father of genetics. He conducted experiments with pea plants and established the fundamental principles of inheritance. Mendel's laws, including the law of segregation and the law of independent assortment, laid the foundation for modern genetics.

3. DNA and Genetic Material

DNA is a double-stranded molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It consists of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The sequence of these bases forms the genetic code.

4. Genetic Variation and Mutations

Genetic variation refers to the differences in DNA sequences among individuals within a population. Mutations are the ultimate source of genetic variation and can be caused by various factors such as environmental influences, errors in DNA replication, or exposure to mutagens.

5. Inheritance Patterns

Inheritance patterns describe how traits are passed from parents to offspring. These patterns include autosomal inheritance, sex-linked inheritance, incomplete dominance, codominance, and polygenic inheritance. Understanding these patterns is essential for predicting the likelihood of certain traits in offspring.

6. Modern Genetics and Biotechnology

Advances in genetics have led to the development of biotechnology, including genetic engineering, gene therapy, and the study of genomics. These fields have significant implications for medicine, agriculture, and various other industries.

7. Genetic Disorders

Genetic disorders result from abnormalities in an individual's genetic material, and they can be inherited or arise from spontaneous mutations. Examples of genetic disorders include cystic fibrosis, sickle cell anemia, Huntington's disease, and Down syndrome.

8. Ethical and Social Implications of Genetics

The study of genetics raises important ethical and social issues, including genetic testing, privacy concerns, genetic discrimination, and the potential for designer babies. It's crucial to consider these implications as genetic technologies continue to advance.

The resources above cover the following skills:

Skills And Processes: The student will demonstrate ways of thinking and acting inherent in the practice of science. The student will use the language and instruments of science to collect, organize, interpret, calculate, and communicate information.

The student will explain why curiosity, honesty, openness, and skepticism are highly regarded in science.

The student will modify or affirm scientific ideas according to accumulated evidence.

The student will pose scientific questions and suggest investigative approaches to provide answers to questions.

The student will test a working hypothesis. (NTB)

The student will use relationships discovered in the lab to explain phenomena observed outside the laboratory.

The student will demonstrate that data analysis is a vital aspect of the process of scientific inquiry and communication.

The student will organize data appropriately using techniques such as tables, graphs, and webs (for graphs: axes labeled with appropriate quantities, appropriate units on axes, axes labeled with appropriate intervals, independent and dependent variables on correct axes, appropriate title).

The student will analyze data to make predictions, decisions, or draw conclusions.

The student will use analyzed data to confirm, modify, or reject a hypothesis.

The student will use appropriate methods for communicating in writing and orally the processes and results of scientific investigation.

The student will use, explain, and/or construct various classification systems.

The student will communicate conclusions derived through a synthesis of ideas.

Concepts Of Chemistry: The student will demonstrate the ability to use scientific skills and processes (Core Learning Goal 1) to explain composition and interactions of matter in the world in which we live.

The student will explain that atoms have structure and this structure serves as the basis for the properties of elements and the bonds that they form.

The student will analyze the structure of the atom and describe the characteristics of the particles found there.

The student will demonstrate that the arrangement and number of electrons and the properties of elements repeat in a periodic manner illustrated by their arrangement in the periodic table.
