Question
Chapter 11.8, Problem 2TC
Summary Introduction
To determine: The probability that a second child of a mother will suffer from Duchene Muscular Dystrophy as her first child (son) is suffering from this disease. She took a DNA test where it was confirmed that she is a carrier for this disease.
Introduction: Duchene Muscular dystrophy is caused due to progressive muscle weakness and degeneration in muscles. It is an X-linked recessive disease. It is caused due to a defect in the synthesis of a gene dystropin, which causes weakness in the muscles of hands and legs in the body. The body muscles get degraded and get filled with connective tissues and fats.
Summary Introduction
To determine: The probability of occurrence of this disease in her daughter as carriers.

A couple, who are both normal, have a daughter who is albino and a son who is normal.
a) what is the probability that their normal son is a carrier of the albinism gene? Show your work.
b) the couple wants to have 3 more children; what is the probability that they will have 3 normal girls? Show your work.
Clara has polydactyly, an autosomal dominant that is 80% penetrant. Clara
inherited her polydactyly from her mother, her father had no polydactyly in his
family. She has an extra toe on her left foot. Her husband Ralph has no
polydactyly in his family.
A) What is the chance that Clara will have a child that will inherit polydactyly?
B) What is the chance that the child will express polydactyly.
You can leave these as un-calculated equations.
Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia.
They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square.
