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?
