a.

Summary Introduction

To determine:

Whether the pattern of baldness will show independent assortment between genetic marker on the X chromosomes and pattern of blandness if the pattern of baldness is sex influenced

a.

Expert Solution
Check Mark

Explanation of Solution

If pattern of baldness is considered as sex-influenced trait, then the genes responsible for baldness must be present on autosomal chromosomes. Thus, the pattern of baldness would independently assort from genetic marker on X chromosomes.

b.

Summary Introduction

To determine:

Whether the pattern of baldness will show independent assortment between genetic marker on the X chromosomes and pattern of blandness, if the pattern of baldness is X-linked recessive.

b.

Expert Solution
Check Mark

Explanation of Solution

If the pattern of baldness is X-linked recessive trait, then the genes of baldness will be present on X chromosomes only. If the genes of baldness and genetic markers are present in close proximity on X chromosome, then they will not assort independently. If they lie far apart, then they will be assorted easily.

Conclusion

Independent assortment between genetic marker on the X chromosomes and pattern of blandness depends upon weather the pattern of baldness gene is sex-linked or X linked gene.

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?
