How is dosage compensation achieved in mammals? What is the name of the process or mechanism by which this is achieved? Be specific in your answer: read through the entire section and summarize. How does this process of dosage compensation explain the patchy coat color pattern of tortiseshell cats (as well as calico cats)? Why are most tortiseshell cats female and not male? In your answer you must provide how the mechanism of dosage compensation explains the basis of coat color. To do this, it would help to include a description of the alleles from coat on the X-chromosome and the possible genotypes/phenotypes associated for males and female cats.
