Answers and explanations

  1. Question: Which gene is primarily responsible for the coat color patterns called merle in many dog breeds?
    Answer: PMEL17
    Explanation: PMEL17 (also called SILV) mutations produce the merle pattern by altering pigment deposition; breeders monitor it because homozygous merle often causes hearing and vision defects.
  2. Question: What physiological mechanism allows dogs to cool primarily through panting rather than sweating?
    Answer: Evaporative cooling
    Explanation: Panting increases evaporation from the tongue and upper airways to dissipate heat; dogs have few sweat glands, unlike humans who rely on widespread sweating.
  3. Question: Which cranial nerve mediates the vomeronasal (Jacobson's organ) sensory signals in dogs for detecting pheromones?
    Answer: Vomeronasal
    Explanation: Sensory neurons from the vomeronasal organ project through the vomeronasal nerve to accessory olfactory structures, aiding social and reproductive behaviors; it's distinct from the main olfactory nerve.
  4. Question: Which breed originated from North Africa and is noted for its blue-black tongue and role as a livestock guardian in harsh climates?
    Answer: Canaan Dog
    Explanation: The Canaan Dog is a primitive pariah-type breed from the Levant adapted to arid environments; blue-black tongues are rarer and often mistaken for Chow Chow traits.
  5. Question: What is the primary physiological cause of exercise-induced collapse (EIC) in affected sporting dogs?
    Answer: Dynamin-1
    Explanation: A mutation in the dynamin-1 gene disrupts synaptic vesicle recycling during intense exercise, causing temporary collapse; it's often misattributed to heat stroke or exhaustion.
  6. Question: Which vitamin do dogs synthesize from cholesterol in their skin when exposed to sunlight, reducing dietary dependence?
    Answer: Vitamin D3
    Explanation: Dogs can produce cholecalciferol (D3) cutaneously, though not as efficiently as humans; deficiency or excess remains a clinical concern in diet formulation.
  7. Question: Which behavioral test measures a dog's ability to follow human communicative cues like pointing or gaze?
    Answer: Social cognition
    Explanation: Social-cognitive tests assess responsiveness to human gestures, reflecting domestication effects; poor performance is often due to lack of socialization rather than cognitive incapacity.
