NURS 6501 ADVANCED PATHOPHYSIOLOGY
WALDEN UNIVERSITY 2026/2027 MIDTERM EXAM
COMPLETE QUESTIONS AND VERIFIED
SOLUTIONS|BRAND NEW!!
How are cells specialized? - ANSWER-through the
process of differentiation or maturation
What is genomic imprinting? - ANSWER-The silencing of a
gene that is 'stamped' with an imprint during gamete
production.
What is epigenetics? - ANSWER-the study of how the
environment affects which genes are expressed
,Recurrence risk for autosomal dominant diseases -
ANSWER-50%
Recurrence risk for autosomal recessive diseases -
ANSWER-25%
What is consanguinity? - ANSWER-marriage between
blood relatives
What gene determines sex? - ANSWER-SRY gene,
typically on the Y chromosome. If a Y chromosome lacks
SRY gene an XY female can be produced, also if an X
chromosome has an SRY gene an XX male may be
produced
,What is a sex-influenced trait? - ANSWER-sex influenced
inheritance are genetic trends based on sex
-i.e. gene that expresses for baldness in men does not for
women
Why would X-linked recessive genes be seen more in
males? - ANSWER-because males need only one copy of
the gene to express the disease
Why are skipped generation diseases seen in X-linked
diseases? - ANSWER-Biologic fathers cannot pass X-
linked genes to their sons and the gene can be transmitted
through carrier females
, What is a sex limited characteristic? - ANSWER-one that
occurs only in one sex
What are polygenic traits? - ANSWER-traits that are
controlled by two or more genes
Prediction of disease - ANSWER-A marker locus, when
closely linked to a disease-gene locus, can be used to
predict whether an individual will develop a genetic
disease.
