Human height heritability study A survey of UNCG Genetics students examined the heritability of human height. It can be shown that, under certain conditions, the slope (b) of the regression of a person's height on the height of their same-sex parent can be used as an estimate of half of the narrow-sense heritability (i.e. b = (1/2)h2).The data are plotted above. Results of the analysis were as follows: males only (number of samples = 12): b = 0.40 (p-value = 0.06) females only (number of samples = 17): b = 0.40 (p-value = 0.26) combined, with adjustment for sex (number of samples = 29): b = 0.40 (p-value = 0.04)
