The Cheetah Problem!

---

     

  

This Chart shows the predicted decline in cheetah population throughout the world. Currently, there are roughly 10,000 cheetahs in Africa and Asia.  The likely extinction of the viable cheetah population is sometime around 2015-2025.  Viability is the key word. A population becomes genetically non viable when the population drops to below 12,000.   It would seem likely that the species will survive but only in limited surroundings, provided captive breeding goes well. The problem of the endangered cheetah is quite complex but the underlying problem is really about human population growth and expansion.

This week we will be learning a little history about genetics and the father of genetics Gregor Mendel. We will also practice what we learned about how parents pass traits on to their offspring using punnet squares.  Finally, you will be introduced to the cell cycle, mitosis, and meiosis.

A.     Read the article and use the link below to answer the following analysis questions in complete thoughts.

http://www.exploringnature.org/db/detail.php?dbID=22&detID=54

1.    Why is Gregor Mendel considered the father of modern genetics?

2.      How did Mendel describe dominant and recessive traits?

3.       How did Mendel explain hybrid plants?

4.       What are Alleles?

5.       What traits did Mendel observe in tall versus short pea plants?

B.     Use the following link to answer the following questions in complete thoughts.  Then practice completing punnett squares until you can do 3 punnet squares perfectly!

http://www.glencoe.com/sites/common_assets/science/virtual_labs/E09/E09.html

1.       Genes that control traits come in?

2.       What are the two types of alleles?

3.       Recessive alleles only show up if?

C.   Watch the video (use the link) and answer the following questions in complete thoughts.

http://www.youtube.com/watch?v=Q6ucKWIIFmg

1. List the phases of the cell cycle.

2. Why do the chromosomes line up in the center of the nucleus?

3. Why is it important for the chromosomes to separate before the cell divides?

Eat your vegetables, before they eat you!

This week we will be learning about genetics. Earlier we learned about traits and characteristics and how they affect the appearance of an organism. This week we will be focusing on inherited traits, genes and alleles. We will also be setting up an experiment that shows how these inherited traits are passed from parent to offspring in plants!

KEY WORDS

Inherited Traits- An inherited trait is a characteristic passed from parents to the offspring or child through genes.

Genes- The basic unit of heredity. Different forms of genes are called alleles.

Alleles-  Alternative form of a gene inherited separately from each parent. (for eye color the allele might result in blue or brown eyes).

KEY CONCEPT: All organisms have genes and inherited traits. 

You have 3 tasks to accomplish for this week's BLOG. 

A. Read the article (use the link) and answer the following questions in complete thoughts.

1. What are inherited traits?

2. How many pairs of chromosomes are found in a human cell? How many genes?

3. How do you know if you have a recessive trait?

 http://www.ehow.com/about_5393500_inherited-traits.html

B. Watch the video (use the link) and answer the following questions in complete thoughts.

1. What is the structure & function of chromosomes?

2. What is the difference between a body cell and a sex cell?

3. How do people get Down's Syndrome?

http://www.ehow.com/video_4984760_how-many-chromosomes-does-each.html

C. Watch the video (use the link) and answer the following questions in complete thoughts.

1. Genes are part of what?

2. Explain how genes are like family recipes?

2. How many chromosomes do the following organisms have:

• humans
• horses
• chimpanzees
• monkey's
• cows
• chickens
• bananas

*If you have time watch genetics 101, part 2 and tell me what SNP's are?
