GUARANTEED PASS/ALREADY GRADED A+
You are breeding a Brother-Sister mating of 2 B6D2F2
mice. The male is brown and the female is tan.
What are the correct Genotype possibilities, (future
offspring) for these two mice? - ....ANSWER...Male's
genotype(s): bbDd, bbDD
Female's genotype(s): bbdd
What is pregnancy toxemia? How can it be treated? -
....ANSWER...Pregnancy toxemia is a condition when the
mother is in an negative energy balance due to the pups
developing. The mother is not getting enough energy
through food and metabolism to keep up. We treat this with
glucose/nutrition supplementation.
,How do we sex mice? - ....ANSWER...By the anogenital
distance, males are 1 ½ X longer than that of females
Guinea Pig IM injection - ....ANSWER...Restrain the
animal appropriately. Place thumb of non-dominant hand
on the vertebrae and index finger just behind the most
caudal rib. Find the epaxial muscle and lift it against your
thumb. With dominant hand, place syringe perpendicular to
the muscle. You will need to move your hand slightly to
look for blood when aspirating.
Mouse SQ Injection - ....ANSWER...Restrain the animal
appropriately
Place the needle, using a cranial to caudal approach at a 40-
45 degree angle into the scruff between the ears.
What type of ovulator is a mouse? -
....ANSWER...Spontaneous
Is a mouse covered by the AWA? - ....ANSWER...No
, What is a mouse used in research for? -
....ANSWER...Cancer
Toxicities
Pharmaceuticals
Breeding
Behavior
What is Malocclusion? What is the cause? How can it be
prevented? - ....ANSWER...Overgrown teeth or where the
jaws do not match up correctly
Malocclusion is most often caused by the animal not
wearing teeth down adequately due to not having
appropriate substrates to chew on
Offering appropriate enrichment to allow the animal to
chew.
Where is the gerbil's scent gland? - ....ANSWER...ventral
midline, just caudal to the Xyphoid Process or Umbilicus
Where is the hamster's scent gland? -
....ANSWER...lateral flank, just proximal to the hip
