###### FREE Expert Solution

Broad Sense Heritability: estimates percentage of genetic variance using all components of genetic variance

: ratio of genotypic variance (VG) to phenotypic variance (VP)

Narrow Sense Heritability: estimates percentage of genetic variance using only additive variance

: ratio of additive genotypic variance (VA) to phenotypic variance (VP)

: used to determine population response to artificial selection ###### Problem Details

The following variances were calculated for two traits in a herd of hogs.

 Trait VP VG VA Back fat 28.9 13.7 7.98 Body length 49.1 27.2 12.4

Part A. Calculate broad-sense (H2 ) heritability for back fat in this herd. Enter your answer to three decimal places (example: 0.123).

Part B. Calculate broad-sense (H2 ) heritability for body length in this herd. Enter your answer to three decimal places (example: 0.123).

Part C. Calculate narrow-sense (h2 ) heritability for back fat in this herd. Enter your answer to three decimal places (example: 0.123).

Part D. Calculate narrow-sense (h2 ) heritability for body length in this herd. Enter your answer to three decimal places (example: 0.123).

Part E. Which of the two traits will respond best to selection by a breeder?

A. back fat
B. body length
