Pedigree Worksheet 3: Hemophilia the Royal Disease: Pedigree Worksheet 3 Hemophilia The Royal Disease Answer Key
A pedigree worksheet is a diagram used to trace the inheritance of genetic traits within a family. It uses specific symbols to represent individuals and their relationships, and to indicate the presence or absence of a particular trait.
The pedigree worksheet for Hemophilia the Royal Disease shows the inheritance of hemophilia, a blood clotting disorder, within several royal families in Europe. The symbols used include squares for males, circles for females, filled symbols for affected individuals, and half-filled symbols for carriers (females who carry the gene for hemophilia but do not have the disorder themselves).
Inheritance Pattern of Hemophilia
Hemophilia is an X-linked recessive trait, which means that the gene responsible for the disorder is located on the X chromosome. Males have only one X chromosome, so if they inherit the hemophilia gene, they will have the disorder. Females have two X chromosomes, so they must inherit two copies of the hemophilia gene to have the disorder.
Carrier females have one copy of the hemophilia gene and one normal copy. They do not have the disorder themselves, but they can pass the gene on to their children. If a carrier female has a son, there is a 50% chance that he will inherit the hemophilia gene and have the disorder.
If she has a daughter, there is a 50% chance that she will inherit the carrier gene.
Historical Impact of Hemophilia in the Royal Families, Pedigree worksheet 3 hemophilia the royal disease answer key
Hemophilia has been documented in several royal families throughout history, including the British royal family, the Spanish royal family, and the Russian royal family. The disorder had a significant impact on the lineage and succession of these families, as affected males were often unable to produce heirs.
In the British royal family, hemophilia was first introduced by Queen Victoria, who was a carrier. Her son, Prince Leopold, Duke of Albany, had hemophilia and died at the age of 31. Her grandson, Prince Albert Victor, Duke of Clarence and Avondale, also had hemophilia and died at the age of 28.
Modern Treatment and Management of Hemophilia
Significant advancements have been made in the treatment and management of hemophilia in recent years. Gene therapy is a promising new treatment that has the potential to cure hemophilia. Clotting factor replacement therapy is another important treatment that can help to prevent and control bleeding episodes.
Genetic counseling is also an important part of the management of hemophilia. Genetic counselors can help individuals and families to understand the risks of passing on the hemophilia gene and to make informed decisions about reproduction.
General Inquiries
What is a pedigree worksheet?
A pedigree worksheet is a tool used to trace genetic inheritance patterns within a family. It employs symbols and patterns to represent affected and unaffected individuals, allowing for the analysis of genetic traits and the identification of potential carriers.
How is hemophilia inherited?
Hemophilia is an X-linked recessive trait, meaning it is carried on the X chromosome. Males, who have only one X chromosome, are more likely to be affected by the condition if they inherit the affected X chromosome. Females, who have two X chromosomes, are typically carriers if they inherit one affected X chromosome.
What impact did hemophilia have on royal families?
Hemophilia had a significant impact on royal families, particularly in the 19th and 20th centuries. The condition was prevalent in several European royal families, including the British royal family, and affected the lineage and succession of these families.
