Question 3 - Which of the following describes a phenotype?  

   Wrong Answer- The number of traits an organism possesses

    Right Answer- An observable product of an organism’s genetic makeup. This is because a phenotype is what shows on the actual organism while the number of traits an organism possesses is the number of traits a certain organism inherits.  

Question 4 - Which of the following describes a genotype?

   Wrong Answer- An observable product of an organism’s genetic makeup

    Right Answer- The genes contained in an organism’s genetic makeup. This is because a genotype is the different genes the genetics makeup has while the observable product is actually a phenotype.

Question 6 - Which of the following is the passing of traits from parents to offspring?

   Wrong Answer- Characteristics

    Right Answer- Heredity. This is the correct answer because a characteristic is like someones mood or how they want to act and none of that is inherited and heredity defines the passing of physical/mental statistics.

Question 10 - If a baby zebra has a two recessive genes for short legs which of the following may be true?

   Wrong Answer-The father has two recessive genes. The mother has two dominant genes.

    Right Answer- The father has two recessive genes. The mother has one dominant gene and one recessive gene.    This is right because......

Dad = 2 recessive                            Dad = 2 recessive

Mom=2 dominant                            Mom = 1 dominant 1 recessive

*Wrong*                                             *Right*

Question 17 - A population of mice lives in northern Canada where there is snow most of the year. 

These mice are hunted by other animals. Which feature would be best for these mice to inherit from their parents, so they are NOT all killed off by their predators?

   Wrong Answer- A large amount of fur

    Right Answer- White Fur Color. White Fur Color is correct because since in northern Canada it snows most of the year the white fur would act as a camouflage to blend in so that the mice wouldn't be killed off.

Question 19 - Two parent bunnies have recessive traits for white fur.  What genotype will all of the offspring have?

   Wrong Answer- Ff

    Right Answer- ff. This is because both parent bunnies have the recessive trait and if you use a punnet square the only possible outcome for a genotype is ff since both parents have recessive traits.

 

Question 22 - What is the probability of two parents that are BB and Bb to have an offspring with a recessive trait?

   Wrong Answer- 25%

    Right Answer-0%   is correct because.....                                                    

 ___B___b__                       

B|  BB  |  Bb |                      

  |_____|___ |                        

B|   BB |  Bb |                      

  |          |       |                          

        There is no bb which would be the genotype for the recessive.
