November 1-5
Dear Students:
This week we will have a test Wednesday, November 03. Remember this test will only include Problems involving:
• Sex-linked traits
• Pedigree charts
• Dihybrid crosses
Your chapter content test will be until next week. For that one you will study the entire chapter content as well as Key Terms.
Helpful Review on Pedigree Analysis
A pedigree is a diagram of family relationships that uses symbols to represent people and lines to represent genetic relationships. These diagrams make it easier to visualize relationships within families, particularly large extended families. Pedigrees are often used to determine the mode of inheritance (dominant, recessive, etc.) of genetic diseases. A sample pedigree is below.
In a pedigree, squares represent males and circles represent females. Horizontal lines connecting a male and female represent mating. Vertical lines extending downward from a couple represent their children. Subsequent generations are therefore written underneath the parental generations and the oldest individuals are found at the top of the pedigree.
If the purpose of a pedigree is to analyze the pattern of inheritance of a particular trait, it is customary to shade in the symbol of all individuals that possess this trait.
In the pedigree above, the grandparents had two children, a son and a daughter. The son had the trait in question. One of his four children also had the trait.

1. Punnett Square examples: Complete MONOHYBRID crosses (That means tracking one trait at a time). We will not be doing Dihybrid crosses in class (that means tracking 2 traits on one large punnett square.)
2. Practice Quiz with answers….just for fun!
3. Practicing Punnett Squares
4. Vocabulary Practice (some of the words here we did not use, but you can ignore those and use the ones we did review.)
5. Genetics Practice Problems. Find out how 2 hearing dogs can produce a deaf dog and others. This site also shows dihybrid crosses (which will not be done in class)
6. Interactive Game with punnett Squares

Practicing Punnett Squares
Practicing Punnett Squares
(Monohybrid Crosses)
--------------------------------------------------------------------------------
Directions: For each of the following problems,
1. List the genotypes of the parents.
2. Diagram and complete a Punnett square
3. Give the phenotype percentages of the offspring.
--------------------------------------------------------------------------------
1. In garden peas, round seed coats (R) is dominant over wrinkled seed coats (r). What will the results be of a cross between a homozygous dominant male and a recessive female.
2. In peas, yellow color (Y) is dominant to green (y). What will be the results of a cross-pollination of a heterozygous female and a heterozygous male?
3. In humans, straight toes (S) is dominant over curled toes (s). What would be the result of a cross between a recessive male and a heterozygous female?
4. In dogs, erect ears (E) is dominate over droopy ears (e). What are the results if two heterozygous dogs have a litter of puppies.
5. The ability to roll the tongue (R) is determined by a dominant gene while the recessive gene results in the inability to roll the tongue (r). A man and his wife can both roll their tongues and are surprised to find that their son cannot. Explain this by showing the genotypes of all three persons. (Note: you do not need to do a Punnett Square for this problem).
6. In humans, wavy hair (CS) results by the co-dominant situation of curly hair (C) and straight hair (S). What are the possible results if a curly-haired man and wavy-haired woman have children.
7. In iris, purple (p) is incompletely dominant over white (w). What would be the results of a cross if both parents were pale lavender (heterozygous-pw)?
8. In crocus flowers, white (W) and purple (P) colors are co-dominant, and result in a purple and white striped flower when both genes are present. What are the possible results from the cross-pollination of a striped crocus with a white crocus?
9. In cattle, red (r) is incompletely dominant over white (w) hides. Roan in the name of the color that results from incomplete dominance. What are the possible results if a white male mates with a roan female?

Dear Students:
We will continue to learn about Genetics and Heredity this week. Practice your Genetic Problems and the Pedigree Charts. Please don't forget to keep your binders organized: file papers, color code and keep important documents in plastic protectors. We are now beginning the Second Quarter and it is a good chance to improve our first Quarter Grade.
Please don't forget that our Science Test for chapter 4 will take place Wednesday, October 20. As you prepare for it, make sure you read the chapter and then study details with the help of your work pack and key terms.
Your final grade for the First Quarter is already posted in Power School. There is always a chance for improvement!!!!
Intelligence without ambition is a bird without wings.

Use all the problems done in class to practice.
Important Dates to keep in mind:
October 11: Holiday
October 13: Test Genetics Problems
October 15: Work pack Due
October 14: End of the 1st Quarter

Dear Students:
This week we are beginning Chapter 4.This Chapter covers many aspects of the science of heredity. We will be learning about
• Mendel’s work
• Probability and heredity
• Inheritance
• The DNA Connection.
Some important dates to keep in mind are:
October 6: Key Terms Ch 6
October 13: Test #1 Chapter 4
October 20: Test #2 Chapter 4
You can notice this chapter is divided into two parts. As we will be taking genetics cases I decided to divide the content in two parts.
Gregor Johann MENDEL was an Austrian monk and biologist whose work on heredity became the basis of the modern theory of genetics. To learn more about him visit:
