Final - Lecture 4

Question 1

Factors to consider regarding selection

Answer 1

• single trait
• multiple trait
• QTL
• Combinations
• What is the goal?
• Collecting info
• parameters
• select the best, mate the best, repeat

Question 2

Single trait

Answer 2

one characteristic at a time (e.g. colour in dogs)

Multiple trait

Answer 3

Many characteristics at once (e.g. height, colour, temperament)
- sometimes breeders try to select for too many things and make little progress

Question 4

What are QTLs useful for?

Answer 4

Quantitative trait locus

- using molecular genetic information (e.g. hip dysplasia)

E.g. Fila Brasileiro

Question 17

Performance dogs

Answer 17

• law enforcement
• rescue/reconnaissance/recovery
• racing
• agility/demonstration/’tricks’

Question 18

Is trainability a genetic trait?

Answer 18

Yes

Question 19

What to consider when breeding a service dog?

Answer 19

• breed type, size, physical characteristics
• behaviour, intelligence, learning ability
• CARAT behaviour assessment
• exploration of novel environment
• exposure to novel stimuli
• reaction to different footing
• reaction to people

Question 20

Predicting a service dog’s success?

Victoria brought sue to Edmonton riding Andy carrying Fraser

Answer 20

Combine visual persistence + biddability + sociability to other dogs + tolerate people + exploratory + reaction speed + arousal + nice confidence + footing

+/- 4 allows for flexibility

Question 21

When breeding dogs, what must be considered?

Answer 21

1. Breed type and breed performance goals
2. performance and service goals
3. purebred breeding programs
4. breed standards and breeding goals

Question 22

Breed type and breed performance goals:

Answer 22

• clubs within CKC
• pursue various goals of the breed
• conformation and various combination of obedience, tracking, agility
• most info recorded in pedigree database

Question 23

Performance and service goals

Answer 23

• skills required for job (specific behaviours, senses, general behaviour)
• conformation soundness (durability, longevity)
• conformation required for job (size, strength, speed, agility, coat type)

Question 24

Purebred breeding programs

Answer 24

• pedigree
• breeding characteristics, conformation
• within population (purebred = closed population)
• relatively little data (often subjective)
• small populations (individual breeders, geography, club size)
• impassioned selection decision making (interpretation of breed standards, breed homogeneity)

Question 25

Breeding standards and goals

Answer 25

How do the standards translate into breeding goals?

• subjective vs. objective (all breeders interpret differently)
• range vs. absolute
• descriptive component
