Question
Chapter 14, Problem 2PDT
Summary Introduction
To determine: The specific data required to detect the situation using dN/dS ratio in the case of paralogs and the pattern observed in duplicative loci using the dN /dS ratio.
Introduction: The origin of two or more genes arising from the process of duplication are said to be paralogs. A hemoglobin gene family is composed of many paralogs which are separated in due course of time. The importance of positive selection can be studied with the help of a simple statistical method (dN/dS) comprising of DNA sequences from two different species.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant
women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their
pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants:
One group take the real medication intended to reduce heartburn, while the other group take placebo
medication. In this study what are:
Independent variable:
Dependent variable:
Control variable:
Experimental group: "
Control group:
If the participants do not know who is consuming the real pills and who is consuming the sugar pills.
This study is
It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months.
The researcher throws out the data from subjects that drop out. What type of bias is there in this study?
If the company who makes the medication funds this research, what type of bias might exist in this
