Abstract:The heritabiligy of fasting glucose was estimated on the members of 50 core families by using the method of correlation and regression of quantitative character heritability so as to research the role of genetic and environmental factors in NIDDM.The result showed that the heritability of glucose,adjusted by age and environmental factors,of the offspring on mid-parent was 0.35768±0.2024.This suggested that in NIDDM genetic factors play a role to some extent,but the influence of environmental factors is more significant,i.e. NIDDM being considered as a multifactorial disease.The genetics of fasting glucose did not show the maternal effects.
