If you wanted to determine an unknown genotype what would you
cross it with? (homozygous dominant, heterozygous, homozygous
recessive)
a. What type of genetic pattern is this an example of?
b. If all the offspring of a large sample showed the dominant
phenotype what type of genotype would the unknown have?
c. If, in a small sample, one offspring showed the recessive
phenotype and the rest had the dominant phenotype, what would
the unknown genotype be?

Problem: Hemophilia is a recessive, sex-linked trait. Use an n to
represent the allele for hemophilia. A woman that has normal blood
clotting and Type O blood marries a man that has normal blood clotting
and a hybrid Type A blood. The woman’s father was known to be a
hemophiliac with Type A blood. Answer the following questions based
on this information.
a. Give the woman’s father’s genotype as completely as can be
determined.
b. What is the woman described as relating to Hemophilia?
c. What are the chances of this couple having a child with
hemophilia?
d. What are the chances of this couple having a daughter with
hemophilia?
e. What are the chances of the couple having a son with blood Type
A and hemophilia?
