ANSC 340 ACTUAL EXAM PAPER 2026
QUESTIONS ANSWERS GRADED A+
◉ For two independent events, the probability that both events
occur simultaneously is the _____ of their individual probabilities.
Answer: Product
◉ In the Labrador Retriever, the yellow coat color is the result of a
recessive genotype masking
the effect of the allele at the B locus. This is an example of interaction
between genotypes at
different loci and referred to as _________. Answer: Epistasis
◉ __________ between these loci is 20%. You create F1's from the
mating AABB to aabb
______ of an "AB" gamete in the F1 could best be described as:
Answer: Recombinant gamete, probability of 0.1
◉ HYPP in horses is an example of this form of inheritance, where
heterozygote is an
intermediate phenotype between the two homozygous phenotypes
Answer: Incomplete Dominance
,◉ P(detection)= 1- (½)n
is true when you test mate your suspected heterozygote with mates
of
this genotype Answer: Homozygous recessive
◉ P(detection)= 1- (3/4)n
is true when you test mate your suspected heterozygote with mates
of
this genotype Answer: Heterozygous
◉ Which type of mate is the most efficient form of progeny testing
(takes the least amount of
progeny to be reasonably confident? Answer: Homozygous recessive
◉ Which type of mate is the least efficient form of progeny testing?
Answer: Homozygous dominant
◉ The process which gametes are formed is termed: Answer:
Meiosis
◉ Why are alleles which are associated with loci far apart but on the
same chromosome not
always in linkage disequilibrium? Answer: Recombination
, ◉ The relationship between linkage disequilibrium (LD), linkage
map distance and
recombination frequency is Answer: Higher theta, greater map
distance, lower degree of LD
◉ Goldendoodles are the product of breeding a poodle with a golden
retriever. The offspring
goldendoodle is technically a Answer: F1 progeny
◉ Codominance in two alleles at a locus on the X chromosome
results in a mosaic phenotype.
An example of this phenomenon is Answer: Tortoiseshell Cat
◉ If a particular genotype is being culled out of a population, the
relative fitness of that
genotype is Answer: Zero
◉ IN an example where we are actively culling all homozygous
recessives from a population,
the selection coefficient "s" for that genotype is Answer: 1.0
