Genetics Exam test questions and answers graded
A+
1. Waardenbur
g Syndrome Cruella de Vil hair and light eyes
Mutation in 6 different genes affect the function of several cell types,
including melanocytes
2. Personalize Mostly autosomal dominant but can be recessive
d medicine
the use of information about a patient's genotype and other clinical data
in order to select a medication, therapy, or preventative measure that is
specifically suited to that patient
3. human pedigrees The pattern of inheritance of a human disorder that is caused by a
mutation in a SINGLE gene can be deduced by analyzing
. Geneticists CANNOT
conduct human crosses in this case.
4. monozygoti
c twins identical twins formed from the same sperm and egg
5. dizygotic twins fraternal twins formed from separate pairs of sperm and egg
6. concordance the degree to which a disorder is inherited, in percentage
7. Heterozygous If the trait is dominant, assume that an attected individual is ,
unless you have a reason to believe otherwise.
8. Polymorphism Two or more common phenotypes of pairs
Ex: ABO groups, taste
9. autosomal
reces- sive attects both male/female
tends to skip one or more generations
, Genetics Exam test questions and answers graded
A+
25% ottspring attected if both parents
Aa 100% ottspring attected if both
parents aa
10. examples of
au- tosomal PKU, cystic fibrosis, albinism
reces- sive
11. autosomal
domi- nant
attects both male/female
appears in every generation
only requires one attected parent
easily confused with x-linked
dominant
12. examples of
au- tosomal
domi- nant
dwarfism, Huntington's, polydactyly, dominant piebald spotting
13. x-linked recessive attects more males than females
all daughters of attected males are carriers but none of the sons receive
the gene
14. examples of color blindness, hemophilia, duchenne muscular dystrophy, testicular
feminization
