, Gene Expression Name something from this module (III) that can be affected by interactions with
other genes(not always but can be).
Protein Product What ultimately dictates which phenotype is expressed?
Phenotype The overall consequence of the activites of the protein produce the ____
Loss of function What type of mutation would cause a gene to lose some OR all of its normal
function?
Hypomorphic What type of mutation would cause a gene to lose only some of its function?
Null What type of mutation causes a gene to lose ALL of it's function?
Haplosufficient If one copy is sufficient enough to produce the wild type then, what type of allele is
that?
Haploinsufficient If both copies of an allele are needed to produce the wild type then what type of
allele would that be?
Gain of function What type of mutation sees the gene acquired deliver a new function or expression?
Loss of Function What type of mutation sees a decrease or loss of expression or function as it relates
to a gene?
incomplete dominance Situation in which one allele is not completely dominant over another allele an
example may be color or size where the allele is not entirely expressed when mixed
with a different allele.
Codominance Both alleles (even though they are different) are expressed completely. Holechek's
favorite example here is blood type.
Incomplete dominance In an example of ____ ____ red flowers are bred with white flowers and produce
pink flowers.
Codominance In an example of ____ ____ An individual who receives the allele for sickle cell
anemia from one parent and the allele for healthy erythrocytes from the other parent
displays a in between erythrocyte that while not as efficient with it's hemoglobin
enables one to stave off malaria.
Coat Color According to the allelic series of the c gene what allele enzyme can be temperature
sensitive?
