Animal Breeding

Front 1

Introduced progeny testing and used inbreeding to fix certain characteristics in animals

Back 1

Sir Robert Bakewell

Front 2

Introduced keeping accurate rwcords of performance of animals so that objective selection became possible

Back 2

Sir Robert Bakewell

Front 3

A test of the value for selective breeding of an individual's genotype by looking the progeny produced by different matings

Back 3

Progeny testing

Front 4

A british agirculturist that developed the new Leicester sheep and used Longhorn cattle for improvement of beef

Back 4

Sir Robert bakewell

Front 5

Leicester sheep is originated from what breed?

Back 5

Lincolnshire breed

Front 6

A british genetecist that showed that the diversity of expression of a trait could depend on the involvement of a large number of so called genes

Back 6

Sir Ronald Aylmer Fisher

Front 7

Founders of theoretical population Genetics

Back 7

Sir Ronald Aylmer Fisher, Sewall Wright, J.BS. Haldane

Front 8

Connected the chromosome theory of inheritance to the works of mendel

Back 8

Thomas hunt morgan

Front 9

The modern father of animal breeding

Back 9

Jay Laurence Lush

Front 10

He based animal breeding not on phenotype but rather on quantitative characreristics and genetic information

Back 10

Jay Laurence Lush

Front 11

Developed the selection index theory and a method using least squares

Back 11

Lanoy Nelson Hazel

Front 12

Developed estimated breeding value and mixed model equations to obtain best linear unbiased predictions of breesing values

Back 12

Charles Roy Henderson

Front 13

Led to the development of many regional types

Back 13

Genetic isolation by distance

Front 14

The development of additional diversity as a result of adaptations to diverse environmenrs

Back 14

Diversity enhancing gene flow

Front 15

Aninals whose breeding and husbandry are controlled by human communities

Back 15

Domestic animals/population

Front 16

Represent either wild relatives of domesticated livestock that are 7sed for food and agri, or populations undergoing domestication

Back 16

Wild populations

Front 17

Animals considered to be feral if they or their ancestors were formerly domesticated

Back 17

Feral populations

Front 18

Breeds that occur only in one country

Back 18

Local breeds

Front 19

Breeds that occur in more than one country

Back 19

Transboundary breeds

Front 20

Transboundary breeds that only occur in one of the seven SoW-AnGR

Back 20

Regional transboundary breeds

Front 21

Transboundary breeds thar occur in more than One SoW-AnGR regions

Back 21

International Transboundary breeds

Front 22

Regions of SoW-AnGR

Back 22

Africa, Asia, Europe n the Caucasus, Latin America n Caribbean, Near n Middle East, North America, Southwest pacific

Front 23

Breeds that have been in the country for a sufficient time to be gemetically adapted to the traditional production systems or environment

Back 23

Locally adapted breeds

Front 24

Form a subset of locally adapted breeds

Back 24

Indigenous, autochthonous or native breeds

Front 25

Breeds that are not locally adapted, comprise both recently introduced breeds and continually imported breeds

Back 25

Exotic breeds

Front 26

Diversity in animal genetic resources popularions is measured in :

Back 26

Interpopulation diversity, Intrapopulation diversity, inter-relationships between populations

Front 34

7th step in bp

Back 34

Evaluation

Front 35

Is conservation through the maintenance of live animal populations

Back 35

In vivo conservation

Front 36

Is conservarion through continued use of live animal populations by livestock keepers in the production system in which the respective populations evolved or are now normally found and bred

Back 36

In-situ conservation

Front 37

Conservation throufh the maintenance of live animals under consitions and outside the area where they evolved

Back 37

Ex sito in vivo conservation

Front 38

Is conservation through the maintenance, under cryogenic donitions, of cells or tissues that have the potential to be used

Back 38

Ex situ in vitro
