Step by step
Solved in 2 steps
- Write down the pros and cons of phenocopying and explain: “No two people are exactly alike. Even monozygotic twins differ from each other”QUANTITATIVE Recall that hemophilia is an X-linked recessive disease. If a woman with hemophilia had children with a man without hemophilia, what is the chance that their first child will have the disease? What is the chance that their first child will be a carrier?INTRODUCTION: Pedigrees are symbolic representations of family relationships and the transmission of inherited traits. For researchers, families are tools; the bigger the family, the easier it is to discern modes of inheritance. Pedigrees apply Mendel’s laws to predict the recurrence risks of inherited conditions. INSTRUCTION: Discuss the pedigree using appropriate terms.
- The role of the TPMT genotype in response to treatment emphasizes the importance of pharmacogenomics. What changes in treatment would be recommended for someone homozygous recessive for TPMT, compared to someone that is homozygous dominant?How is pedigree analysis used to determine whether a trait is inherited in an autosomal-dominant, autosomal-recessive, or X-linked pattern?Explain the difference between X-linked recessive traits and X-linked dominant traits. What are the possibilities that a female child will be affected and express each of the traits?
