Victoria was the first known carrier of haemophilia in the royal line. http://en.wikipedia.org/wiki/Queen_Victoria#Within_Britain
One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.
No. It is a disease carried and transferred through the female line. Tsarina Alexandra passed it on to her only son, Tsarevich Alexi, from her Grandmother - Queen Victoria of the United Kingdom.
Queen Victoria of England who reigned from 1837 - 1901 was the first of the royals to carry the gene.

Hemophilia is a genetic disorder that is usually inherited in an X-linked recessive pattern. It can appear to skip a generation when a carrier female passes the gene to her son, who then expresses the disorder. However, it doesn't truly skip a generation as the gene is passed on in each generation.
The genes that contain the information for the cells to make the clotting factors 8 and 9 are located on the X chromosomeWomen have two copies of the X chromosome (XX); those with a faulty clotting factor gene on one X chromosome and a working copy on the other partner X chromosome are genetic carriers for haemophilia and would not usually be affectedMales have only one X chromosome and a Y (XY); those with a faulty clotting factor gene on their X chromosome will have haemophilia as they have no working gene copy on the Y chromosomeFor men and women to have the same amount of genetic information produced in their cells, one X chromosome copy is usually randomly 'switched off' or inactivated in a woman's cells. In about 10% of women who are genetic carriers for haemophilia, this 'switching off' system results in more of her cells containing the active X chromosome carrying the faulty clotting factor gene copy than the working copy, so she may be mildly affected with haemophilia
Queen Victorias contributions to Britsh Society and etc is she witnessed a revolution in Britsh Goverment huge industrial expansion and the growth of a worldwide empire.
The gene for haemophilia is located on the X chromossome, and can be passed by haemophiliac or carrier mothers to sons (more common) or daughters. Haemophiliac fathers will always have carrier (but not necessarily affected daughters.)

"Like most recessive sex-linked X chromosome disorders, haemophilia is more likely to occur in males than females. This is because females have two X chromosomes while males have only one, so the defective gene is guaranteed to manifest in any male who carries it. Because females have two X chromosomes and haemophilia is rare, the chance of a female having two defective copies of the gene is very remote"
An organism can have/carry a gene but without espressing this gene.
