Group Number: 1

Male Genotype: BB Male Blood Type: B

Female Genotype: AO Female Blood Type: A

I. Complete the Punnett Square below after you are given your random mating:
(Enter Here)**__ B ||= __**Allele 2 - Male (Enter Here)**__ B || (Enter Here)**__ A ||= (Enter Here) AB ||= (Enter Here) AB || (Enter Here)**__ O ||= (Enter Here) BO ||= (Enter Here) BO ||
 * = X ||= __**Allele 1 - Male
 * = __**Allele 1 - Female
 * = __**Allele 2 - Female

1.) What are the possible blood types of the offspring from these parents? AB or B

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

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 punnett square for a male and a female and complete it.

(Enter Here)**__ X ||= __**Allele 2 - Male (Enter Here)**__ Y || (Enter Here)**__ X ||= (Enter Here) XX ||= (Enter Here) XY || (Enter Here)**__ X ||= (Enter Here) XX ||= (Enter Here) XY ||
 * = X ||= __**Allele 1 - Male
 * = __**Allele 1 - Female
 * = __**Allele 2 - Female

1.) What are the probabilities (in percent) of the offspring being male or female? 50-50

2.) Explain your answer to question #1.

III. Going even 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.

2.) What is the percentage chance that an offspring will be a female? Explain.

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

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

IV. Going even further, further:
Create your own scenario like the one above in "Going Further". Create three questions based upon your scenario. Make sure that you have checked the questions over such that you can figure out the answers!!!
