In this chapter, we focused on a mode of inheritance referred to as quantitative genetics, as well as many of the statistical parameters utilized to study quantitative traits. Along the way, we found opportunities to consider the methods and reasoning by which geneticists acquired much of their understanding of quantitative genetics. From the explanations given in the chapter, what answers would you propose to the following fundamental questions:

How do we assess environmental factors to determine if they impact the phenotype of a quantitatively inherited trait?

Video transcript

Hello everyone and welcome to today's video. So which of the following factors must be control to determine genetic variation. So let's say that we are studying, We're conducting this study aimed at studying the genetic variation of a specific gene. So we have this group of people and we want to achieve consistency to make sure that our results are as accurate as possible. If you want to achieve consistency, we want to make sure that all people are exposed to the same type of environment. So things such as tax ins, diet, sunlight exposure and many other factors that could affect the genes of this person need to be controlled as much as possible to make sure that our results are as reliable as they can be. Now all of these factors are said to the environmental factors as they refer to the environment of each person. So if we want to study genetic variation, this is something that we definitely have to control. So that correct answer choice for this question here is going to be answer choice. I really hope this video helped you and I hope to see you on the next one.
