In a study of coat colour in beach mice, researchers measured the darkness of the fur on the backs of 50 breeding pairs and their offspring performed a regression of offspring phenotypes on midparent values. The slope of the regression was 0.67 and the regression explained 75% of the variation. Question= What is the narrow-sense heritability estimate
