BIOD 171 Microbiology Final Newest Version Real Questions
and Verified Answers 100% Correct (A+) | UPDATED ACTUAL
Exam Questions and CORRECT Answers

Question 1.
MC1R

Correct Answer: Melanocortin-1 receptor, gene that helps determine skin and
hair color


Question 2.
KIT receptor

Correct Answer: allows melanocytes to be present all over the body


Question 3.
mutations in KIT receptor

Correct Answer: can cause white patches


Question 4.
Epistasis

Correct Answer: interaction between alleles in which one allele hides the
phenotypic effects of another allele


Question 5.
locus

Correct Answer: Location of a gene on a chromosome


Question 6.
TYRP1

Correct Answer: tyrosinase-related protein 1


Question 7.
When crossing 2 genes, will be have 4 distinct possible genotypes?

Correct Answer: Yes if it is AaBb, no if it is AAbb or aaBB.


Question 8.
Mendel's Law of Segregation

, Correct Answer: the two alleles of a gene found on each of a pair of
chromosomes segregate independently of one another into sex cells. only one
allele per gene goes into each gamete.


Question 9.
Mendel's Law of Independent Assortment

Correct Answer: the inheritance of one character has no effect on the
inheritance of another. the alleles of different genes assort independently of
one another.


Question 10.
autosomal recessive

Correct Answer: two copies of an abnormal gene must be present in order for
the disease or trait to develop, can skip generations, affects males and female
equally


Question 11.
autosomal dominant

Correct Answer: only need one copy of the allele to show the trait, do not skip
generations, affects males and females equally
• X linked recessive -✓✓males are affected more often than females, only
females can be carriers, can skip generations


Question 12.
X linked dominant

Correct Answer: only need one affected X to pass on the trait, affected dads
will pass it on to 100% of their daughters and 0% of their sons, since dads give
the Y which determines the Childs sex. affected females will pass it on to
about 50% of offspring (male and female)


Question 13.
Y-linked traits

Correct Answer: only affect males, and affect all sons of an affected male, not
common


Question 14.
x deactivation

Correct Answer: Equalizes gene expression between XX+XY, one X is turned
off in each XX embryo at the 500-1800 cell stage, 50% of the paternal and 50%
