Question
Chapter 7, Problem 13AQP
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
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
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.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions.
1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction?
2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe:
a) What molecule do you recommend for the trial. Why?
b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?
3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale.
4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale.
