Group Number: 1

Male Genotype: AB Male Blood Type: AB

Female Genotype: AO Female Blood Type: A

I. Complete the Punnett Square below after you are given your random mating:

 * = X ||= **__A__** ||= **__B__** ||
 * = **__A__** ||= AA ||= AB ||
 * = **__O__** ||= AO ||= BO ||

1.) What are the possible blood types of the offspring from these parents? Explain. A, AB, and B because of the punnett square.

2.) What are the probabilities of each of these blood types? Explain. 50% A, 25% AB, 25% B.

II. Going a step further:
In humans there is a gene which controls gender. There are two alleles, X and Y. Males have are XY. Females are XX. Create a punnet square for a male and a female and complete it.


 * = X ||= **__X__** ||= **__Y__** ||
 * = **__X__** ||= XX ||= XY ||
 * = **__X__** ||= XX ||= XY ||

1.) What are the probabilities (in percent) of the offspring being male or female? Explain. 50% male and 50% female, because 2 of the 4 squares are XX and the other 2 are XY.

III. Going even further:
a. Create your own scenario like the one above regarding blood type in humans. Enter the scenario below. b. Create three questions based upon your scenario. Enter the questions below. c. Make sure that you have checked the questions over such that you can figure out the answers!!!

Scenario: Two people mate, one has genotype AB and the other genotype BO.

Questions: 1. What are the possibilities for the offspring's genotype? 2. What are the percentages for each blood type? 3. Why would a person want to have genotype AB?

IV. Going even further, further:
A man with blood genotype AO (Blood Type A) and a woman with genotype AB (Blood Type AB) marry and have three children.

1.) What is the percentage chance that an offspring will have blood type A? Explain. 50 2.) What is the percentage chance that an offspring will be a female? Explain. 50 3.) BONUS 1>>>> What is the percentage chance that the offspring will be a female with blood type A? Explain.

4.) BONUS 2>>>> What is the percentage chance that the offspring will be a male with blood type B? Explain.
