Examples of polygenic inheritance in humans include traits such as skin color eye color hair color body shape height and weight. The inheritance of these variants from ones parents helps explain why children usually grow to be approximately as tall as their parents but different combinations of variants can cause siblings to be of different heights. Heritability allows us to examine how genetics directly impact an individuals height. 148 to 193 lbs. The role of environmental factors especially nutrition is estimated to be around 20 40. 124 to 147 lbs.
Aptly called giant for the. Scientists are getting closer to the answer with new results from a large scale genetic study. For example if you are a 510 male estimating your ideal weight with the devine formula you would add 23 10 kg to 50 kg to get 73 kg or 161 lbs. To calculate the wthr a person should divide their waist size by their height. 5 97 to 127 lbs. 4 11 94 to 123 lbs.
These measurements can be taken in a healthcare providers office or at home using a tape measure and scale. For example a population of white men has a heritability of 80 percent and an average height of 178. All of the formulas have the same format of a base weight given a height of 5 feet with a set weight increment added per inch over the height of 5 feet. 4 10 91 to 118 lbs. 143 to 186 lbs. Polygenic and multifactorial our understanding of the role played by genes in many human characteristics is advancing rapidly in for example body size performance on iq tests and personality traits.
These numbers come from estimations of the heritability of human height and from research examining what proportions of the height variation are determined by genetics. Height and weight must be measured to calculate bmi. If the answer is 05 or less the chances are that they have a healthy weight. Because height is determined by multiple gene variants an inheritance pattern called polygenic inheritance it is difficult to accurately predict how tall a child will be. H ow much of height can be traced to the genes inherited from mom and dad. The answer is that about 60 80 of the individuals height is determined by genetics.
119 to 142 lbs. A woman who is 5 feet and 4 inches. Polygenic traits distribution polygenic traits tend to result in a distribution that resembles a bell shaped curve with few at the extremes and most in the middle. It is most accurate to measure height in meters and weight in kilograms. The inheritance of height and weight can best be described as. However the bmi formula has been adapted for height measured in inches and weight measured in pounds.
