Cross a normal vision male (XNY) and a normal vision female that is a
carrier of the recessive allele for color blindness (XNX
n
). Show all work
and tell the phenotype of each offspring. (Give the percentages of each.)
2. Cross a color-blind male and a normal vision female that is a carrier of the
recessive allele for color blindness. Show all work and give the
percentages of each type of offspring.
3. Cross a non-hemophiliac male (XHY) and a non-hemophiliac female that is
a carrier of the recessive allele for hemophilia (XHX
h
). Show your work and
give the percentages of each type of offspring possible.
4. Cross a hemophiliac male and a carrier female. Show your work. What
are the chances that the couple will have a child with hemophilia?
5. Cross a male with a normal immune system (XIY) and a female who is a
carrier of a recessive allele coding for the absence of an immune system
(XIX
i
). Show all work. What are the chances that the couple could have a
child with Immunodeficiency syndrome?
