How is your height determined by both your genetics and the environment?

This question can be rephrased as: “How much variation (difference between individuals) in height is attributable to genetic effects and how much to nutritional effects?” The short answer to this question is that about 60 to 80 percent of the difference in height between individuals is determined by genetic factors.

How does genetics play into height?

The main factor that influences a person’s height is their genetic makeup, or DNA. However, many other factors can influence height during development, including nutrition, hormones, and medical conditions. Scientists believe that DNA is responsible for about 80\% of a person’s height.

What genes decide height?

These genes (and the conditions they are associated with) include FBN1 (acromicric dysplasia, geleophysic dysplasia, Marfan syndrome), GH1 (isolated growth hormone deficiency), EVC (Ellis-van Creveld syndrome, Weyers acrofacial dysostosis), and GPC3 (Simpson-Golabi-Behmel syndrome).

Is height determined by gender?

Men and women generally have similar-sized bodies, but men tend to have longer legs. “That’s why there is a difference in height between men and women – because the legs are so important in determining height,” she explained. A person’s height depends on both genetic and environmental influences.

What factors determine height?

The main factor that influences a person’s height is their genetic makeup. However, many other factors can influence height during development, including nutrition, hormones, activity levels, and medical conditions. Scientists believe that genetic makeup, or DNA, is responsible for about 80\% of a person’s height.

How much of your height is determined by your genes?

These regions, they say, could hold the rest of the variants that have yet to be discovered. It’s believed that up to 80 percent of a person’s height is determined by genetics; however, the research shows that it’s not just genes directly related to bone growth that are associated with growing tall.

What are the advantages of studying genetic variants of height?

The advantage of studying these rare variants is that they tend to have more dramatic effects on height, so scientists can more easily identify exactly how the genes are impacting height. The common variants may be affecting growth plates, the sections of bone where growth occurs, Hirschhorn says, or the overall size of embryos.

Why is it difficult to predict the height of a child?

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.

What is the relationship between height and risk?

Height is correlated with risk to certain diseases and various socio-economic outcomes. As an easy to observe and measure trait, it has been a classic paradigm in the emergence of fundamental concepts regarding inheritance and genetics. Resemblances in height between relatives suggest that 80\% of he … Genetics of human height
