Use the following information to complete the Punnet square and answer the questions
Females XHXH=normal, XHXh=normal (carrier) XhXh=hemophilia Males XHY=normal XhY=hemophilia complete the punnett square with a man with normal blood and a woman carrier
To complete the Punnett square, we need to cross the genotypes of the man (XY) with the woman (XhXh).
Males:
X Y
Females:
Xh Xh
To create the Punnett square, we will combine each possible allele from the man (X, Y) with each possible allele from the woman (Xh, Xh).
The Punnett square would look like this:
Xh Xh
-----------------------
X | XX Xh
|
Y | XY Yh
Now, we can answer the questions:
1. What are the possible genotypes of their children?
From the Punnett square, the possible genotypes of their children are:
- XX: Females with normal blood
- XY: Males with normal blood
- XhX: Females who are carriers for hemophilia
- XhY: Males with hemophilia
2. What is the chance of having a son with hemophilia?
From the Punnett square, we can see that there is a 50% chance of having a son with hemophilia, as there is a possibility of obtaining an XhY genotype.
Note: The lowercase letter 'h' represents the hemophilia allele, and the uppercase letter 'H' represents the normal allele.
