NURSE 445 LIBERTY UNIVERSITY GENETICS QUESTIONS AND
ANSWERS | NURSE 445 GENETICS STUDY GUIDE & PRACTICE
TEST 2026/2027
genomics - correct answer ✔✔the study of the organization, function, and evolution of genomes
Genes cause of death - correct answer ✔✔plays a role in 9/10 deaths related to <3, cancer, stroke,
diabetes, Alzheimer’s
Genes - correct answer ✔✔the basic physical and functional unit of heredity. composed of DNA and
code to make proteins. Genes themselves DO NOT cause the disease but the mutation does!
Autosomes - correct answer ✔✔chromosome pairs 1-22
Sex chromosomes - correct answer ✔✔number 23 XX or XY
aneuploidy - correct answer ✔✔gain or loss of chromosomes from the normal # 23 pairs, 46 individual
copy number variation - correct answer ✔✔most people of 2 copies with 1 from each set of parents, but
some people have 1, 3, or more copies instead.
Copy number variation results from insertions, deletions, and duplication's of large segments of DNA and
can effect proper body function
inherited mutations - correct answer ✔✔from germline cells- sperm or egg. from conception so every
single cell in that persons body is effected. Life long
Acquired (Somatic) - correct answer ✔✔not in every cell of the body because does not stem from
conception cells. can be environmental or developed throughout lifespan. can be acute or chronic
Mosaicism mutations - correct answer ✔✔occurs in young embryo, ma not see change from a normal
person, it is only come of their cells when dividing that have it
polymorphism - correct answer ✔✔>1% of genes, can have little to no effect or can be beneficial like
prevent from getting disease (malaria)...could lead to make vaccine for others
Single Gene/ Monogenic - correct answer ✔✔rare, autosomal dominate, autosomal recessive, x linked
recessive
Chromosomal/ polygenic - correct answer ✔✔occur in many diff chromosome parts ex: abnormal
number (aneuploidy), turner syndrome, HTN
Family history - correct answer ✔✔important to obtain, want at least 3 generations involved!
, Having 1 or more blood relatives who have been effected by a condition esp. in the younger ages it is an
indicator hat a family member is at risk for developing the condition
Autosomal Dominant Disorder - correct answer ✔✔Huntington's
Neurofibromatosis-1
Familial hyperlipidemia
Von Hippel Lindau syndrome
only 1 parent need to have it in order for the child to get it
Autosomal ReCessive - correct answer ✔✔CystiC fibrosis
siCkle Cell anemia
Both parents need this in order to pass it on bc need two recessive to show the trait, but only one to be
a carrier
X-linked Dominant - correct answer ✔✔Fragile X syndrome
only need one parent to have it because it is dominant
X-linked Recessive - correct answer ✔✔Hemophilia
Duchenne Muscular Dystrophy
need two bc it is recessive, if only one they are a carrier
Sickle Cell anemia - correct answer ✔✔autosomal recessive
African/ african american
mediterranean
Tay-Sachs disease - correct answer ✔✔Ashkenazi Jew
French canadian
cystic fibrosis - correct answer ✔✔caucasians
familiar hyperlipidemia - correct answer ✔✔afrikaners
french canadian
lebanese
finns
African americans - correct answer ✔✔most diverse= hard to track and treat
sickle cell
diabetes
stroke
prostate/breast/lung cancer
asthma
HTN
Distrust healthcare system
