What happens to the instructions when the genes are changed or mutated Provide an example of hemoglobin gene mutation?
If our hemoglobin gene is normal, the hemoglobin protein works fine. But if the instuctions in that gene are changed, or "mutated,"changes in the hemoglobin protein could result. One such mutation causes a disorder called sickle cell anemia.
What gene or chromosome is mutated in the hemophilia disorder?
Hemophilia is most often caused by mutations in the F8 gene, located on the X chromosome. This gene provides instructions for making a protein called factor VIII, which is essential for blood clotting. Mutations in the F8 gene can result in reduced or absent levels of factor VIII, leading to the characteristic bleeding problems seen in hemophilia.
Royal hemophilia is the result of inheritance?
Yes, royal hemophilia, also known as the "Royal disease," is a hereditary bleeding disorder caused by a mutation in the gene responsible for producing a blood clotting protein. It is inherited on the X chromosome. Because males have only one X chromosome, they are more likely to express the hemophilia trait if they inherit the mutated gene.
What is the main difference between hemophilia and sickle cell anemia in the way in which it is inherited?
Hemophilia is inherited in an X-linked recessive pattern, meaning it primarily affects males who inherit the affected X chromosome from their carrier mother. Sickle cell anemia is inherited in an autosomal recessive pattern, meaning both parents must pass on a mutated gene for the child to develop the condition regardless of gender.
What are two diseases linked to the X chromosome?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
Hemophilia is caused by a mutated allele that produces a defective form of the protein hemoglobin?
False, Sickle Cell Disease :))
Is caused by a mutated allele that produces a defective form of the protein hemoglobin.?

Did Stacy Romanov and her sisters have hemophilia?
Grand Duchess ANASTASIA and her sisters were probably carriers of the hemophilia gene but did not suffer from the effects of hemophilia. Males suffer from hemophilia. In rare cases girls do suffer but that is only when both parents carry the mutated gene
Females who are carrier for hemophilia?
Females who are carriers of hemophilia possess one normal and one mutated allele of the gene responsible for the disorder, typically located on the X chromosome. While they often do not exhibit severe symptoms of hemophilia due to the presence of the normal allele, they can experience mild bleeding problems and have a 50% chance of passing the mutated allele to their offspring. Male children who inherit the mutated allele will be affected by hemophilia, while female children may become carriers themselves. Genetic counseling is recommended for carriers to understand the risks for future generations.

Why is hemophilia more likely to be fatal in women than in men?
Hemophilia is generally more severe in males because it is an X-linked recessive disorder, meaning that men have only one X chromosome, while women have two. If a woman possesses one defective gene for hemophilia on one X chromosome, she may still have a functional gene on her other X chromosome, often resulting in milder symptoms. However, if a woman inherits two mutated X chromosomes, she can experience severe hemophilia, leading to a higher risk of fatal complications compared to men. Additionally, women with hemophilia may face challenges related to reproductive health and bleeding during childbirth, increasing the potential for life-threatening situations.
Cancer results from a malfunction of what?
Cancer starts out as a single cell deviding into a mutated cell, which then devides more and more and more until you have a mass of defective, mutated cells, which can no longer preform there job, massing in a single area.
What are two sex-chromosome disorders?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
What do you get when you cross a male hemophiliac with a female hemophiliac?
The gene for hemophilia A is found on the X chromosome (it is a sex-linked recessive disorder). Women have two X chromosomes and men have one X chromosome. A woman with hemophilia (very rare) would have the mutated gene on both of her X chromosomes. This means that all of their children, both male and female would have hemophilia.
What happens to haemoglobin in sickle cell anaemia?
Hemoglobin molecules are mutated, thus giving the red blood cells an abnormal, rigid shape.
What does NOT affect hemoglobin's affinity for oxygen?
Hemoglobin's affinity for oxygen is not directly affected by factors such as the presence of carbon dioxide in the bloodstream or the pH level of the blood. While these factors can influence the oxygen-binding capacity through the Bohr effect, they do not change the intrinsic properties of hemoglobin itself. Additionally, the genetic structure of hemoglobin, unless mutated, remains constant and does not affect its affinity.
What would happen if the code for a protein that allowed your blood to clot was mutated?
Nonfunctional blood clotting agent will result in a case of hemophilia, and any cut or bruise must be taken very seriously.
