Unit 9: Classical Genetics: Mendel's experiments
Reading
OpenStax book: Ch. 8 - "Patterns of Inheritance"
BJU: 5B - "Basic Genetics" and Ch. 6A - "Chromosomal and genetic changes"
AP: Green book Ch. 12 "Mendel's Experiments" and Ch. 13 "Modern Understandings of Inheritance". The two chapters go together; most of the 'hard stuff' is covered in Ch. 12.
Topic
Labs
Memo: 2020-2021 labs will include hands-on and virtual, and may vary as the Covid-19 situation changes.
Here is a list of possible labs for this lesson. I will choose from this list when we get here.

Topic
- The laws of inheritance as developed by Mendel around 1865
- The modern understanding with chromosomes, etc.

Here is a list of possible labs for this lesson. I will choose from this list when we get here.
- Artificial Selection using Wisconsin Fast Plants (fulfills the AP "dirty dozen lab" #1). A 2-month lab that can be done at home.
- There are many other Genetics labs from a variety of sources
- Or we could get a head-start on the more-involved Molecular Biology labs which begin in the next session

Introduction
In the previous Unit, you started to learn about genetics by studying the process of meiosis, which occurs in sexually reproducing organisms (humans, whales, and pea plants). In meiosis, you begin to see how the genetic material is divided up between offspring, and how genes get reshuffled and redistributed during meiosis I and II.
In this Unit, we will continue studying genetics by looking at the laws of inheritance. This area of biology is known as classical genetics - or Mendelian Genetics - named after Gregory Mendel and his famous experiments on pea plants in the 1800's.

When studying heredity, we make use of "Punnett Squares" like this one
LABS & HOMEWORK BELOW: There are numerous labs, projects, presentations, and homework exercises posted on this portal. Don't panic. Some of these are current, some are left over from prior years, and some are just "parked" here for future use. DO NOT WORK ON A LAB OR HOMEWORK EXERCISE unless it has been assigned in your weekly class email! Due to the 2020-2021 Covid-19 situation, I will assign labs and homework as we go along based on what we are able to do.

Upcoming Genetic Disorder class presentations
"Research a genetic disorder of your choosing, what causes it genetically, and any drugs, procedures or devices used to treat or manage it". At this stage, I am just looking for your IDEA, stated with enough specificity that I can comment and give some feedback.

Forensic DNA Fingerprinting lab: Digestion and Electrophoresis of Crime-Scene DNA
In this 3-part lab project, we will analyze the DNA from a Crime Scene using restriction enzymes and gel electrophoresis.
The DNA-fragments from 5 "suspects" will be compared to DNA found at the Crime Scene.
This is a very important technique used in criminal justice, ancestry & anthropology research, paternity, human remains identification, and disease tracing.
