Question

Assignment Objectives:

When given a family’s genetic history, deduce the genotypes for specific

family members.

•Describe the inheritance and expression of various genetic disorders found in humans.

•Determine how genetic screening and counseling can be used to help

counsel individuals dealing with lethal genetic disorders in their family.

Read through each scenario and answer the following questions:

a. Determine the genotypes of all individuals discussed in each

scenario in addition to yours, your partners’, and your unborn child.

For example, “You remember your partner telling you that their father

died at an early age of Huntington’s disease.”

In this case you would need to determine your partner’s father’s genotype.

b. Determine what probability your unborn child will inherit the

disorder (be sure to include a Punnett square)?

i. If you are unable to determine your child’s chance of inheriting

the disorder what additional information do you require?

c. Are you worried about your or your partner’s risk of inheriting the disorder (this is particularly a concern for Huntington’s disease and

Marfan Syndrome)?

Scenario

Your father is red-green colorblind, and you are wondering if this could

affect your child’s ability to see colors. Although your father has lead a

productive life, you want to know what the chances are your own child will

also be red-green colorblind.(there is no history of colorblindness in your

partner’s family, there is no history of color blindness in you mother’s family, the outcome of this scenario will depend if you are a male or female.)
