What is the nickname for hemophilia?
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).
What statement is true of sex linked inherited disease such as hemophilia?
Sex-linked inherited diseases, such as hemophilia, are primarily caused by mutations on the X chromosome. Because males have only one X chromosome (XY), they are more likely to express these conditions if they inherit the affected X, while females (XX) may be carriers if they have one affected X but typically do not express the disease unless both X chromosomes are affected. This pattern of inheritance leads to a higher prevalence of hemophilia in males compared to females.
What is the pattern of heredity shown in the transparency?
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.
What is the inheritance pattern of a trait controlled by many genes like skin color?
Multiple gene inheritance. Sree
An inheritance pattern in which a gene has more than two alleles?
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.
What is the Inheritance pattern of hemophilia?
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.
Is hemophilia a sex-linked inheritance disease?
Yes, hemophilia is sex-linked.
How many males represented by this pedigree have hemophilia?
To determine how many males have hemophilia from a pedigree, you would need to examine the inheritance pattern shown in the diagram. Hemophilia is an X-linked recessive disorder, so it primarily affects males. Count the males that are shaded or marked in the pedigree to identify those with hemophilia. Without the specific pedigree, I can't give an exact number.
Royal hemophilia is the result of what inheritance?
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.
What are some examples of sex-linked traits?
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.
What is the nickname for hemophilia?
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.

Red-green colorblindness and hemophilia are two human genetic disorders that are caused by?
X-Linked Inheritance
Why is hemophilia a sex-linked gene?
Hemophilia is considered a sex-linked gene because it is primarily associated with the X chromosome. The genes responsible for hemophilia A and B are located on the X chromosome, and since males have one X and one Y chromosome (XY), a single recessive allele on the X chromosome can lead to the condition. In contrast, females have two X chromosomes (XX), so they would need two copies of the recessive allele to express hemophilia, making it less common in females. This pattern of inheritance is why hemophilia is classified as a sex-linked disorder.
What are two sex-linked traits present in humans?
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.
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
What does race does hemophilia affect?
Hemophilia affects individuals across all races and ethnicities; however, it is most commonly associated with males of European descent due to its X-linked inheritance pattern. The condition is caused by mutations in genes responsible for blood clotting factors, which can occur in any population. While the prevalence may vary, hemophilia does not discriminate based on race. Awareness and access to treatment are crucial for all affected individuals, regardless of their racial background.
Who is the man who discovered the pattern of genetic inheritance?
Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance
