Problem
A breeding group has a breeding stock of foxes; on average the foxes will let strangers walk up to within 32m (+/- 11m sd) of them before they scoot off. She uses a set of foxes that have an average 21m escape distance to breed the next generation. When those new pups are raised to adulthood they have an average escape distance of 26m. What's the estimated heritability of escape distance?
