Answer:
In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>
Explanation:
Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.
Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.

Answer:
Staining
Explanation:
In order to make cells or certain features of a cell more visible under the microscope, scientists use specific stains. These stains bind to certain features in a cell, allowing better distinction. For example, iodine is a common stain used in plant cells, as it turns blue/black in the presence of starch, which is abundant in plant cells.
