Q3. Select a trait of interest. A. What was the trait? (1 point)B. What is the phenotype for the
trait, and is this the dominant or recessive allele for the trait? (2 points)C. What are the possible
genotypes for the parents? (2 points)D. Include the results of one Punnett square, showing a
possible combination between alleles for the trait from the parents by filling in the genotypes
according to the numbers in the square, above. (4 points)E. Based on the cross, what percent of
children born to the parents would express the trait? (1 point)--Answer below:
Q4. Create a Punnett square to determine the possibility of a couple having a color-blind child if
the mother has the recessive trait on one X and the father is color-blind. HINT: Use Xb to
indicate an X with the color-blindness trait. How many female offspring will be color-blind?
How many male offspring? (5 points)--Answer below:
Q5. What was the case number of the student’s karyotype? What was the result of the student’s
karyotype? (Include the sex andthe chromosomal disorder, if applicable. If there was no
chromosomaldisorder, the student must state that the individual was normal.) (5 points)--Answer
below:
Q6. Give an example of a situation in which it would be important to create a karyotype for an
individual. Explain. (5 points)--Answer below:

points)--Answer below:
Q8. Does a karyotype tell all of a person’s genetic characteristics? Explain. (5 points)--Answer
below:
Q9. Why is a photograph of cells in metaphase for performing a karyotype? (5 points)--Answer

important to know if one is a carrier? (5 points)--Answer below:
Q11. From the hemophilia procedure: (4 points)A. What were the possible genotypes of the
offspring?B. What is the probability of males having hemophilia?C. How many females would
have hemophilia?D. How many carriers would there be?--Answer below:
Q12. Explain why more males tend to suffer from X-linked disorders than females. (5 points)-Answer below:
Q13. The student has a friend that knows the student is taking Biology, and she is confused about
her blood type. Her blood type is O, but her dad is A and her mother is B. She asks the student if

it is possible for her parents to have a child that is O. Explain the answer to her. (5 points)-Answer below:
Q14. In a flower garden, the student has purple and white pansies. The student notices that a new
pansy has sprouted. When it finally flowers, the pansy is lavender. Explain how this happened. (5
points)--Answer below:
Q15. With a botanist friend’s help, the student decide to cross the lavender pansy with the white
pansy. Will this result in any purple pansies? Explain. (5 points)--Answer below:
