Which is true about narrow-sense heritability?

Broad-sense heritability measure which of the following component of phenotype?

A regulatory mutation in the PAX3 gene in a population of horses causes the gene to be abnormally expressed in tissues where it is normally silent, disrupting melanocyte migration during embryonic development. This leads to white spotting patterns and congenital deafness due to improper development of pigment and auditory structures. The mutation affects both coat color and auditory system development because of its misexpression in multiple cell lineages during embryogenesis. Which of the following terms apply to this condition? (Select all that apply)

A sheep producer wants to improve fleece weight in their flock of Merino sheep. In the current flock, the average fleece weight is 8.2 pounds per ewe. The estimated heritability (h²) of fleece weight in Merinos is 0.35. The producer selects a group of the highest-producing ewes, all of which produced 10 pounds or more, and finds the mean fleece weight of the selected group is 10.4 pounds. If this producer breeds amongst this selected group, what is the expected response to selection (R) in the next generation?
