Summary Introduction

To review:

The additional cross that might help in determining whether the Mendel’s model is valid for genes of horse and provide an explanation for the experimental cross performed along with the phenotypic frequencies that might be obtained from it. Further, explain the rationale behind the why the proposed cross model will provide the test of the model proposed by Mendel with respect to blending-inheritance.

Introduction:

According to the blending inheritance theory, the progeny of the parents produce offspring with the average characteristic of the parents. However, in contrast to this, Mendel proposed the particulate hypothesis of inheritance, on the basis of which the traits are inherited in discrete form. According to Mendel theory, the genetic integrity of the parents is always maintained. A particular researcher did not believe the hypothesis proposed by Mendel as when he crosses a chestnut horse (reddish-brown) with a cremello (very light-colored) horse, he always obtained an intermediate color horse, palmino (golden-yellow).

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?
