LARORATORY EXERCISES IN GENETICS
a. On the basis of this pedigree, what do you think is the most likely mode of
inheritance for Duchenne Muscular Dystrophy? ceklinkeol rerdy
오오모모
b. If couple ll-7 and Ill-8 have another child, what is the probability that the child will
have Duchenne Muscular Dystrophy?

c. If IlII-2 and III-7 mated, what is the probability that one of their children would
have the disease?
3.
Consider the pedigree diagram of phenotypes below:
a Assuming the shaded individuals have an autosomal recessive trait, count the
individuals with:
homozygous genotype:
heterozygous genotype:
unknown genotype:
A man with a specific unusual genetic trait marries an unaffected woman arnd they
have four children. Pedigrees of this family are shown in parts (a) through (c), but
the presence or absence of the trait in the children is not indicated. For each type
