| Abstract: | The human stature and weight are influnced by both heredity an'd environment factors, they are polygenic inheritance. This article analysed mean. coefficient of variation, regression and correlation of both the characters for 224 middle-school students from 12 to 16 years old and 213 pre-school children in BeBei district, Chongqing. The estimates of heritabilities of both the stature and weight of both middle-school students' and pre-scho9l students', using the parent-child regression, were 0.5993 and 0.3659, respectively. |
