Environmental issues include -People living in cold climates tend to have larger bodies than people living in warm climates and -Modernization is associated with an increase in stature (Option 3 and 4), while genetic factors include thousands of genes have minuscule effects on height and-"Tall" alleles are more common in northern European populations, and "short" alleles are more common in southern European populations and (Option 1 and 2).
The expression of genetic and environmental factors acting on the phenotype means that different classes of factors influence the development of a given phenotypic trait such as in the case of height which is associated with certain alleles and also with the environment due to the diet.
Therefore, with this data, we can see that genetic and environmental factors acting on the phenotype mean that these two classes of factor may alter a phenotype and therefore we have into account both classes in order to determine the phenotype of complex traits such as height and or weight.
Complete question:
Human stature varies within and among groups and is affected by both genetic and environmental factors. Identify which of the following pieces of evidence show that genetic factors influence height, and which show that environmental factors influence height.
-"Tall" alleles are more common in northern European populations, and "short" alleles are more common in southern European populations.
-Thousands of genes have miniscule effects on height.
-Modernization is associated with an increase in stature.
-People living in cold climates tend to have larger bodies than people living in warm climates
