Meiosis &Genetic Inherited Diseases

1. Meiosis &Genetic Inherited Diseases

3. You should pick a role of one of the four members that form your genetic counselor team: As a BiologistAs a Social worker As a Genetic Engineer As a Geneticist • You will be responsible for: • Preparing written answers to the guiding questions. • Presenting the five minutes explanation for your role in the presentation day.

4. Meiosis & The Genetic Disorders • The so-called 'DNA Revolution' has allowed the medical world to diagnosis diseases in unborn babies. Some of these disorders result from errors during meiosis or mutation in the genetic code. Parents of many families who were informed that their infants will likely suffer from a genetic disorder are desperately need the help of a genetic counselor team to understand and deal with the situation properly. They need the help of your team.

5. As a Biologist • As a Biologist, you should present an illustration of the cell division, how genes are inherited through the process of meiosis, how babies get half of their chromosomes from each one of their parents and discuss the results of the errors that may happen during meiosis. You should cover the following guide questions: • What is DNA? What is its chemical structure? What is the relation between DNA, genes, and chromosomes? • What is meiosis? Describe the different phases of meiosis? When and where it happens in the human body? • Explain oogenesis and spermatogenesis? why do you think cytoplasmic cleavage is equal in spermatogenesis, but unequal in oogenesis? What is the advantage of having one ovum and four sperms in meiosis? • What is crossing over? When it happens? What is the significance of it? What is meant by the terms synapsis and chiasma? • What is independent assortment process? What role does it play in producing unique characteristics? What is aneuploidy and euploidy? • Explain the role of meiosis in an organism's sexual life cycle? Discuss the relationship between sex and reproduction.

6. As a Genetic Engineer • As a Genetic Engineer, your role is to investigate the potential cure of the disorder. You should cover the following guide questions: • What is DNA? What is its chemical structure? What is the relation between DNA, genes, and chromosomes? • What is meiosis? Describe the different phases of meiosis? When and where it happens in the human body? • Explain oogenesis and spermatogenesis? why do you think cytoplasmic cleavage is equal in spermatogenesis, but unequal in oogenesis? What is the advantage of having one ovum and four sperms in meiosis? • What is the perfect time for gene testing? On which chromosome the disorder is located? What are the possible options that the parent may have if they do the gene testing before, after starting a family? • What are the current accepted treatments for the disorder?  Include early detection programs, counseling, physical therapy, and/or drug therapy which might be applied to this disease. • What are the experimental treatments now available due to the incredible progress of the Human Genome Project         ( include all possible cures and all research being conducted today in regards to this disorder.)

7. As a Social worker • As a Social worker, you should research any possible ethical issues involved with this disorder. You should inform the parents about privacy issues and fair practices in using genetic information. You should cover the following guide questions: • What is DNA? What is its chemical structure? What is the relation between DNA, genes, and chromosomes? • What is meiosis? Describe the different phases of meiosis? When and where it happens in the human body? • Explain oogenesis and spermatogenesis? why do you think cytoplasmic cleavage is equal in spermatogenesis, but unequal in oogenesis? What is the advantage of having one ovum and four sperms in meiosis? • What are the social cost of the genetic disease on the personal, marital, parental, family, group, and community level? What is everyday life like? What is the quality of life?  • According to your understanding of social suggestion, moral obligations, and the legal consequence of genetic manipulation and treatment, what is the course of actions that the parent may think about which seems to be appropriate in view of their risk, their family goals, and their ethical and religious standards? • What are some organizations that can help a family cope with a child's disorder (Examples: experimental therapy, institutional care, and whether the parents should have more children)

8. As a Geneticist • As a Geneticist, your role is to explain the disorder to the parents. You should cover the following guide questions: • What is DNA? What is its chemical structure? What is the relation between DNA, genes, and chromosomes? • What is meiosis? Describe the different phases of meiosis? When and where it happens in the human body? • Explain oogenesis and spermatogenesis? why do you think cytoplasmic cleavage is equal in spermatogenesis, but unequal in oogenesis? What is the advantage of having one ovum and four sperms in meiosis? • What makes the disease genetic? What are the causes of it? How does a person inherit it? What are the possible genotypes of the parents? • What are the effects and symptoms of the disease? Is it dominant or recessive? What are the chances of a person with this disease passing it to the next generations?  • What is the life expectancy of someone with the disease? How common is the disease in the population
