Question

Which of the following statements are true and why?

1. More accurate selection ca not improve the change of breeding values per generation.

2. Narrow-sense heritability is the accuracy of predicting breeding value from a single performance record on the individual.

3. If the narrow sense heritability is low, we need a large amount of progeny to allow the regression coefficient used to predict breeding value to approach 2 (the max) when the source of information is the average of single records on its progeny.

4. BLUP (best linear unbiased prediction) allows larger scale genetic evaluation for a population of organisms.

Answer 1

Answer:- 4 BLUP (best linear unbiased prediction) allows larger scale genetic evaluation for a population of organisms.

BLUP is the preferred method for large-scale genetic evaluation, Most often the evaluation of large populations, typically entire breeds ,Filed data - data that are regularly reported by individual breeders to breed associations or government agencies Large scale genetic evaluation of breed and entire population. Best linear unbiased predictor is a statistical method for predictions from genetically diverse contemporary groups.
