n. A gene located on an X-chromosome.

How are X linked genes inherited?

http://answers.yahoo.com/question/index?qid=20090225144058AA2pSu3

They are inherited from the X-chromosome, which is an X chromosome. The mother always donates one of the X chromosomes. If the father donates a X, then the baby is female. If the father donates a Y, then the baby is male. If a gene is locat…

Why can’t males be carriers in X-linked gene inheritance What is …?

A carrier is an individual which is heterozygous (greek, roughly translating; ‘different’ ‘genes’) for a certain trait, eg: Bb. The dominant gene will be expressed and the organism will appear no different from a homozygous dominant individ…

Q: . Hypospadias, a birth defect in male humans in which the urethra opens on the shaft instead of at the tip of the penis, results from an autosomal dominant gene in some families. Females who carry the gene show no effects. This birth defect is an example of: (a)an X-linked trait, b. a Y-linked trait. C. a sex-limited trait d. a sex influence trait or e. genetic effect? Explain your answer.

A: Answer C. According to the question, hypospadias is a result of an dominant gene, therefore carsch explanation is not true, because it is only true for recessive traits. It can’t be a Y-linked trait because women would not possibly carry the gene, since women does not carry Y. So I conclude it can’t be A or B. Sex-limited trait appears in only one sex, and sex influence appear in both, but differs. Since the defect does not appear in women at all, it’s c. I don’t think genetic effect is a scientific term. This is a genetic defect, but genetic effect is nonsense talk.

Q: Only answer if you have seen Lorenzo’s Oil. Otherwise, just….just go away.1. Show how Lorenzo’s parents used a scientific method to solve their problem. State the problem, ask a question and use examples from the film to illustrate the steps.2. From the description of the disease, ALD, sketch what Lorenzo’s neurons most likely looked like a year after being diagnosed. 3. ALD is a recessive sex-linked of X-linked disease. What are the probable genotypes of the family members listed? Aunt #1, Aunt #2, Aunt Dee, Michaela, Augusto, Lorenzo.4. What is Lorenzo’s Oil? How does it work? Use the sink model from the film.5. Explain Augusto’s use of paper clips to represent good and bad fatty acids. What did his dream help him understand?6. Why did the medical community resist the Odone’s treatment ideas? Why did the parent support groud resist? Give examples of arguments for and against. 7. How do analogies help you to understand the scientific problem? How did modeling help solve the scientific problem? How did modeling help solve the scientific problem? Can you think of other great discoveries that employed the use of models?8. Did the family’s courage and persistence inspire you? How?9. How did Augusto and michaela demonstrate “life-long” learning?10. Defend the position that diseases that affect a small % of the population should not get as much money for research as the big killers like cancer and heart disease.11. Why did olive oil not work completely? Trace the developments in the different kinds of oils discovered.12. What do you think is the role of support groups? How did the support group affect the Odones?13. What was found out from the Polish biochemist? What was the purpose of the ALD Symposiums? What happens when scientists work in isolation? 14. What is erucic acid?15. Where was the myelin research being done? What was the experiment? How could this research help Lorenzo?16. Did the treatment for ALD really happen by accident? Explain other times in medical history where an important discovery happened by mere chance.17. Why is there a difference between the results with Lorenzo and the results reported by the children at the end of the movie?18.

A: 1) True2) SRY, protein Testes Determining Factor3) 50% heterozygous carriers, 25% affected, 25% normal (provided all the zygotes have the same survivability)4) 1 for the male… complicated for the female due to X-inactivation… however, the answer is probably meant to be 2.5) Hemophilia, Becker Muscular DystrophyGave you 5, others can do the rest.
