What are some examples of x-linked genes

Health related question in topics X linked .We found some answers as below for this question “What are some examples of x-linked genes”,you can compare them.

A:An excellent example of an X-linked gene is the one coding for factor VIII. Factor VIII is a protein, that is essential to blood clotting. People who do not have factor VIII have a condition called hemophilia. [ Source: http://www.chacha.com/question/what-are-some-examples-of-x%26%2345%3Blinked-genes ]

What is X-linked gene?
n. A gene located on an X-chromosome.
How are X linked genes inherited?
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.

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.
