Chapter 16, Problem 1PDT
Summary Introduction

To explain: The evidence that incomplete lineage sorting (ILS) has affected DNA variation in humans, chimpanzees, and gorillas.

Introduction: Incomplete lineage sorting is a factor that makes it difficult to determine the phylogenetic relations between the radiation species. Radiation species are those species that descended from a common ancestor in a short time period. ILS has chances to be common between the commonly related species.

Explanation of Solution

Incomplete lineage sorting is said to occur when a phylogenetic tree developed using a single gene that has differences compared to the tree developed for population or species level. ILS can come as a problematic cause for determining phylogenies because of its increased frequencies. Studies have shown common ancestry between the humans, chimpanzees, and the gorillas. Molecular studies show that ILS has a significant effect on the DNA variation of these species. ILS has caused polymorphism to inherit in two or more species that are descended from the same common ancestor. For example, studies have shown a significant relation between six alleles of humans and 4 alleles of chimpanzees of the same gene at “major histocompatibility” loci A and B. These two-locus are found in both the species and indicate that these loci have arose the method of gene duplication in their common ancestor before speciation.

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 research work?
