Hemophilia is a sex linked gene carried in the x chromosome.
The nickname for hemophilia is "the royal disease" because it was prevalent in European royal families due to the genetic inheritance pattern of the disorder. Hemophilia is a rare genetic bleeding disorder that impairs the blood's ability to clot properly, leading to prolonged bleeding and easy bruising. It is caused by a deficiency in clotting factors VIII (hemophilia A) or IX (hemophilia B).
The pattern of heredity shown in the transparency is most likely a familial inheritance pattern, where certain traits or genetic conditions are passed down through generations within a family. Examples of familial inheritance patterns include autosomal dominant or recessive inheritance, X-linked inheritance, or mitochondrial inheritance. These patterns help geneticists and researchers understand how genetic traits are transmitted from parents to offspring.
Multiple gene inheritance. Sree
Polygenic inheritance is an inheritance pattern in which a trait is controlled by multiple genes, each with two or more alleles. This results in a continuous range of phenotypes rather than distinct categories.
Hemophilia is caused by a deficiency of clotting factor VIII (hemophilia A) or clotting factor IX (hemophilia B).
If the father has hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of having hemophilia and a 50% chance of being a carrier. It is very rare for both parents to have these defective genes.If the father does not have hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of being carriers.If the father has hemophilia and the mother has normal blood, all sons will be normal and all daughters will be carriers.
Yes, hemophilia is sex-linked.
Hemophilia is broken into three subcategories; Hemophilia A, Hemophilia B, and Hemophilia C. These subcategories designate a person as having a deficiency of one of three specific clotting proteins. Hemophilia A is the deficiency of the protein called Clotting Factor VIII. Hemophilia B is the deficiency of Clotting Factor IX. Hemophilia C is the deficiency of Clotting Factor XI. "Royal" hemophilia is simply a reference to Hemophilia B and is therefore a result of a deficiency in the Clotting Factor IX protein. It is sometimes called the royal disease because it has been known to have been passed through some royal families throughout history.
Some examples of sex-linked traits include color blindness, hemophilia, and male pattern baldness. These traits are carried on the sex chromosomes, with color blindness and hemophilia being more common in males due to their inheritance on the X chromosome.

X-Linked Inheritance
Two sex-linked traits present in humans are color blindness and hemophilia. These traits are carried on the X chromosome and are more commonly expressed in males due to their inheritance pattern.
The inheritance pattern of the BRCA1 gene is dominant.
Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
