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?

	back fat
	body length
