Biology Assignment for Sex-Linked Traits

1. Visit the following link: http://www2.edc.org/weblabs/SexDetermination/sexdetermination.html



2.Post a comment that includes the following:

a. Your general reaction to the site

b. At least two specific things you liked about the site.

c. One suggestion for improvement.

d. An answer to the following question:
Two students are arguing over which parent is most responsible for producing a male offspring which shows a sex-linked recessive trait (such as colorblindness). Student #1 argues that the mother is most responsible because boys get their only X chromosome from their mother. Student #2 argues that the father is responsible because he gives the "Y" chromosome to his son and, therefore, doesn't contribute another "X" that might possibly cover up the recessive allele he got from his mother. Which student you think is correct and WHY?

Biology Extra Credit

The Assignment:
1. Visit each of the following links and read the material.

http://www.accessexcellence.org/AE/AEPC/NIH/gene09.php
http://www.accessexcellence.org/AE/AEPC/NIH/gene10.php
http://www.accessexcellence.org/AE/AEPC/NIH/gene17.php

http://www.accessexcellence.org/AE/AEPC/NIH/gene20.php

2. Write response to this post at least one paragraph in length in which you thoroughly address the following in your OWN words:

Like virtually everything else in the world, genetic testing has its "pros" and "cons". Based on what you have read and your own personal feelings, would you want to be genetically tested? Why or why not? (Do the "pros" outweigh the "cons" or vice-versa?)

Be sure to include specific examples based on ideas from the readings (in your own words, of course).

Due Date/Time: No later than midnight on Thursday, March 25, 2010

Evaluations of Punnett Square Links

Visit at least one of the links posted by someone else in the class. Act5ually read and/or use the site (if interactive). Then post your evaluation of the site. I want to hear both positive and negative comments, BUT phrase your negative comments in a form like: "The site would be better if...." and NOT "This site is bad because...". The purpose of this evaluation is CONSTRUCTIVE criticism (to help find improved sites)!

Punnett Square/Genetics Links

Please post at least one GOOD (and preferably interactive) link that deals with how to use Punnett Squares to predict the traits of offspring in genetic crosses. BE SURE TO INCLUDE AN ANNOTATION (brief description of the site AND why the link is worth visiting!)

"Better" Links for Env Sci

Please post the URL for your "improved" link along with an explanation of why it is better.
