Genetics -  DNA From the Beginning - Modules 1-5

When you click Submit (at the bottom of this web page) it will save your work on the server for me.

Each person is responsible for their own work. If you work with someone else you need to think carefully about each answer and re-write it in your own words.

You may want to write the answers in word (or some other wordprocessor) and cut and paste them into the boxes when you are ready to submit.

TAB OR USE THE MOUSE Between the fields....

The "form handler" software doesn't like "blanks" so, if you don't have an answer, leave the -No answer- in the box.

You will want to keep this window open while you work on DNA from the Beginning. To do this you should open DftB in a new window.

Question 1: What is a pistil? Which matures first, in a pea plant, the female or male sex organs? How did that facilate Mendell's experiment? Why is Mendell called the father of genetics?

Read Module 2-

Question 2: Are any people purebred for any traits? Give me at least one example of a human genotype and a human phenotype. Mendell taught H.S. science. How was he different from Dr. G?

Question 3: Pea plants are either tall or short. Most human traits do not show this either/or inheritence pattern. We will learn why latter, however, for now, identify at least one human trait that you either have it or don't.

Question 4: Is there a necessary relationship between dominance and frequency? (That is are dominant traits necessarily more common.-Hint, think eye color in Sweden.)

Question 5: What is the genotype of yellow peas? of green peas? 

Remember, the boxes will expand as you type if you need more space.

Look up achondroplastic dwarfs. 

Question 6: If two achondroplastic dwarfs have children what would be the ratio of dwarfs/normal offspring at (a) conception (b) age 5? Explain.

Question 7: Were Mendell's numbers too perfect?
