Explanation:

2. Polygenic ( poly- many) traits are the genetic traits that are governed by several genes. Human height is one such example. Other examples in humans are skin color, eye color, etc.

3. There are 3 alleles responsible for the blood type in humans, which are  

Thus, when both the alleles for A blood type and B blood type are present, both are expressed as A and B antigens on the surface of RBC because of Codominance (Co- together) thus producing AB blood type.

4. The pH of the soil is an environmental factor. Hence, the change of color based on the soil pH is an example of the environment affecting a genetic trait.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
