Dave is a botanist. He's analyzing a new species of plant that grows more than 6 feet in height. The average height of this plant is normally 5 feet. To

determine whether height is genetic, Dave breeds the tallest plants, which are 7.5 feet tall. If, heritability = response / selection, what's selection?

Heritability is a statistic used in breeding and genetics works that estimates how much variation in a phenotypic trait in a population is due to genetic variation among individuals in that population. Other causes of measured variation in a trait are characterized as environmental factors, including measurement error. In human studies of heritability these are often apportioned into factors from "shared environment" and "non-shared environment" based on whether they tend to result in persons brought up in the same household more or less similar to persons who were not.
