A mouse geneticist selected for increased 12-day litter weight (total weight of a litter of offspring 12 days after birth) in a
wlad13 [49]

Answer:

12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection

Explanation:

Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.
