This is a preview. There are 5 more flashcards available for chapter 1

What is selective breeding?Only use males and females for breeding that have passed a certain quality criterion
-
What is the predefined goal of animal breeding?To genetically improve the population in a certain direction
-
What is a good definition of animal breeding?Animal breeding involes the selective breeding of domestic animals with the intention to improve desirable (and heritable) qualties in the next generation
-
What is a trait?A distinguishing phenotypic charasteristic, typically belonging to an individual.
-
What is a phenotype?That what you observe or measure on the animal for a certain trait
-
What are the prerequisites for domestication?1 - The animals should be able to adaopt to the type of feed they are offered by humans. This may be different from what they were used to in the wild
2 - Animal must be able to survive and reproduce in relative closed quarters of captivity. Animals that need a very large territory are not suitable to domesticated
3 - Animals need to be naturally calm. Very skittish or flighty animals will be hard to prevent escaping
4 - Animals need to be willing to recognise humans as their superior, which means they must have flexible social hierarchy -
What is progeny testing?The method of evaluating performance of the first (small) group of progeny and use that information to select the best father of future progeny
-
What is a breed?A group of animals of a certain species that through generations of selective breeding has become uniform in performance, appearance and selection history
-
What is a species?The largest group of animals that are capable of interbeeding and producing fertile offspring
-
What is the negative correlated response?When selective breeding has not only improved certain performances, but simultaneously and unintendidly also deteriorated other performances that were not under selection
