Punnett Squares and Genetics

    
Be sure to add the notes I emailed to you into your One Note!  Try these "practice problems" out using a Punnett Square.

C=curly hair (UPPER CASE "C")
c= straight hair (lower case "c")

1. If the Mom is HETEROZYGOUS curly (Cc) and the dad is HOMOZYGOUS straight (cc), what are the possiblities for their offspring?  Give in percentages.


2. If the mom and dad are both Homozygous Dominant, what will the outcomes be for their offspring?


3. Both parents are heterozygous.  Could they have a child with straight hair???

(Answers are in the file cabinet! :)

If you need a little tutorial, check out this video for Punnett Square help!  You only need to watch the first 5 minutes of it!  We have not covered the rest of the video yet!  It will be helpful later though!
