Questions and Answers
  • 1. 
    What percentage of offspring will have cystic fibrosis if both parents are heterozygous for the cystic fibrosis gene?  What percent will be carriers?  What percent will be neither carriers or be affected? Show your punnett square and answer EACH of these questions on your sheet of loose leaf paper.  Type "OK" in the box below so that your computer will accept this question. 
  • 2. 
    Could a man with type B blood and a woman with type AB produce a child with type O blood?  Explain all of the possible resulting genotypes and phenotypes from ths cross.  Show the punnet squares (man could have two possible genotypes) and answer the questions on your paper.  Again, type an OK in the box below to move on.
  • 3. 
    If a man and a woman, both with normal vision, marry and have a colorblind son, what must the genotypes of both parents be?  If the man dies and the woman remarries to a colorblind man, what type(s) of vision could be expect to have from her second marriage?  How many/what percentage of each type of vision could be expected?  Again, show both punnett squares and the resulting phenotypes of the offspring on a loose leaf piece of paper.  Type an OK in the box below to move on. 
  • 4. 
    Write an argumentative paragraph on whether you do or do not beleive we should be eating (or that it is safe to eat) genetically modified food.  You MUST follow the format for an argumentative paragraph.  You can locate the format on your 8th grade page.  Write this on your loose leaf piece of paper.  Type OK in the box to move on.
