Breeding value calculation

Question 1

Which parameter does not depend on the population mean?

Answer 1

Distribution

Question 2

Which is untrue for the genetic merit

Answer 2

its value is depending on the actual environment

Question 3

Which is true for the special breeding value

Answer 3

it is a certain type of breeding value when next to the additive gene effects the non-additive gene effects (dominancy, epitasis) too are regarded in the computation (it has great importance in the hybridization)

Question 4

What is not valid for the valuable traits?

Answer 4

Computed traits are unrealistic for the herd improvement because these are not directly recordable

Question 5

Of what is the abbreviation BLUP?

Answer 5

Best Linear Unbiased Prediction

Question 6

Which is not true for the correlation coefficient?

Answer 6

its values got in negative range refer to lack of association

Question 7

Which statement is improper regarding the heritability estimate?

Answer 7

it was discovered by Ch. Darwi

Question 8

Which is an example for multiple threshold traits?

Answer 8

Scrapie

Question 9

Which is true for the breeding value?

Answer 9

it is a deviation of the individual genetic merit from the mean genetic merit of a reference population

Question 10

Which allelic interaction will not cause deviation from the expected performance?

Answer 10

additive interaction at the same locus
