100% pass
,Loss of Function - ANSWER-What type
of mutation sees a decrease or loss of
expression or function as it relates to a
gene?
incomplete dominance - ANSWER-
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 - ANSWER-Both alleles
(even though they are different) are
expressed completely. Holechek's
favorite example here is blood type.
Incomplete dominance - ANSWER-In an
example of ____ ____ red flowers are
bred with white flowers and produce
pink flowers.
,Codominance - ANSWER-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 - ANSWER-According to the
allelic series of the c gene what allele
enzyme can be temperature sensitive?
Complementation test - ANSWER-
method of discovering whether two
mutations are in the same or separate
genes
, Yes - ANSWER-If two mutant parents
are to produce a wild type in their
progeny then do the mutation
complement each other?
Complementation - ANSWER-In one
example two alleles are on separate
genes and a certain phenotype is
expressed. In the next generation
however, the offspring has both alleles
on the same gene and the phenotype is
no longer expressed. What is this an
example of?
epistatic - ANSWER-Gene interaction
occurs when two or more genes affect
the same phenotype. What type of
interaction is this?
9:7 - ANSWER-What ratio indicates two
genes interacting in the same pathway?
