Human Genetics Lab Report
Name, date, course and section required for password:
The lab report is unique each semester and checks have been put into place to ensure students are doing
their own work. Copying from other students or from outside resources will result in a zero on the
accompanying lab quiz.
I. Inheritance of Human Genetic Characteristics
1. Give an example of a human trait that shows incomplete dominance.
2. Refer to Lab Exercise 1. After completing the coin flip activity, draw what the
resulting child would look like. Sign, date and prepare an image your drawing and
include it with this lab report.
3. According to the information in Lab Exercise 1, in a random sample of 100 babies
born of heterozygous parents, what percentage do you predict would have freckles?
4. What is a pedigree and how is it useful?
5. In the pedigree in Lab Exercise 2, what percent of the F2 generation have free
earlobes?
6. How many pairs of autosomes do humans have?
7. Give two examples of an X-linked disorder.
8. When looking at a pedigree, how can you tell if an individual is a carrier of an
autosomal recessive trait?
9. In Lab Exercise 3, how many of the F2 generation have sickle-cell anemia?

10. What is Hemophilia-A and how is it passed to one’s children?
11. Refer to Lab Exercise 4. What percent of the F2 females are carriers of color
blindness?
12. An individual has type A blood. What genotypes are possible?
13. In a case of disputed paternity, a child is type O, and mom is type B. Fill in the
information below and use Punnett squares to determine the possible blood types of
the father.

2. Queen Victoria of England was a carrier of the genetic disorder which causes
hemophilia A. The following diagram is a partial pedigree of her family. How many
of her daughters were carriers?
3. A mother has a small nose and a father has a medium size nose. Use the Punnett
square to determine the possible genotypes of their children.
4. Four siblings are tested for their blood type. Two are heterozygous for type A, and
the other two have type AB. What are the genotypes of the parents?
