What are the chances of hydrops fetalis recurring if only the mother has alpha thalassemia trait?
It is unlikely.
Can thalassemia develop at the age of 20 years?
Very unlikely. Thalassemia is an inherited disease, affected persons are born with the genetic disorders. However, silent carriers (Alpha Thalassemia, 1 gene defect) or Beta Thalassemia Trait (1 gene defect), do not have significiant symptoms. Consequently, if this person did not have any relevant blood tests till the age of 20, he/she might no be aware of having the condition. That's only a hypothetical suggestion.
Can children get sickle cell?
Only if they have 2 parents with the trait(gene) or disease
What are the chances of getting hemophilia?
You can get it from your mom if she has the trait but that only apply to men, if your a girl you have to inherited it from your mother and father.
What is X-linked and Y-linked inheritance?
These are traits that are linked to the sex chromosomes. Only males can get Y-linked traits because only males have a Y chromosome. (Note: it's a bit more complicated that even this explanatin, but this is the general idea) If the father has the X-linked trait he can only pass it down to daughters. If the mother has the trait, the daughter might not have the trait because the father's donated X-chromosome might have a gene that masks it. If a son gets donated an X-chromosome from the mother with the trait, he will definitely show the trait.
What is alfa-thalassamie?
Anemia These drugs include epoetin Alfa (Procrit, Epogen, and Eprex) and darbepoetin Alfa (Aranesp).... The two major forms are thalassemia minor and thalassemia major (Cooley's anemia, beta thalassemia).....What Is Thalassemia?(also known as Mediterranean anemia, or Cooley's Anemia) is a genetic blood disease. People born with this disease cannot make normal hemoglobin (anemia) which is needed to produce healthy red blood cells.Who carries Thalassemia?People of Chinese, South Asian, Middle Eastern, Mediterranean or African origin.What is Thalassemia Minor?People with a thalassemia mutation only in one gene are known as carriers or are said to have thalassemia minor. Thalassemia minor results in no anemia or very slight anemia. People who are carriers do not require blood transfusion or iron therapy, unless proven to be iron deficient.What is Thalassemia Major?Children born with thalassemia major usually develop the symptons of severe anemia within the first year of life. Lacking the ability to produce normal adult hemoglobin, children with thalassemia major:- are chronically fatiqued- fail to thrive, and- do not grow normallyProlonged anemia will cause bone deformities and eventually will lead to death within the first decade of life. The only treatment to combat severe anemia is regular blood transfusions.How can Thalassemia be treated?Regular blood transfusions allow patients with thalassemia major to grow normally and be active. Unfortunately, transfusions result in deadly accumulation of iron in the hearts and livers of patients by their teenage years. If the excess iron is not removed then the patients may suffer from a premature death due to iron overload.Nowadays, drugs designed to remove excess iron (iron chelators) have significantly changed the prognosis of thalassemia major. Patients can grow and develop normally, with relatively normal heart and liver functions. Adult patients are living into their forties and some have children of their own.Despite improved prognosis, many patients find the nightly 10 hour infusions difficult or painful and are reluctant to comply with their doctor's orders. These patients are not free of risk and may die prematurely due to iron overload.Current treatments allow thalassemia patients to live relatively normal lives, however, a cure remains to be found. The genetic cause of thalassemia was one of the first genes discovered in the 1970's, yet 30 years later, gene therapy still eludes thalassemia patients.Do you carry Thalassemia?Many people from the areas of the world where thalassemia is common carry the gene for it on one chromosome (that is, they have thalassemia minor). You may believe that your blood has been tested for this specific gene but testing for thalassemia requires a special blood test. To be tested your doctor must order a blood test called HEMOGLOBIN ELECTROPHORESIS which can identify a carrier of thalassemia.If you, your parents or ancestors are from an area of the world where thalassemia is common, PLEASE REQUEST hemoglobin electrophoresis blood test from your doctor.It is important to identify yourself as a possible carrier of thalassemia (thalassemia minor). A person with thalassemia minor has a 25%(1 in 4) chance of having a baby with THALASSEMIA MAJOR if his/her mate also has thalassemia minor. http://www.thalassemia.ca/viewarticle.asp?aID=31&searchQ=F.A.Q
When a trait has more then two alleles and how is that trait inherited?
Even though there are more than two alleles, an individual can inherit only two, one from the mother and one from the father.
What is the only way a recessive trait will be expressed?
Breed/use only organisms showing the recessive trait for starters. If one of the parents or progenitor lines show the dominant trait then don't use their offspring. If the offspring of one of the oranisims show the dominant trait then remove both the parent of this offspring and this offspring showing the dominant trait from your program.
Can people with hemophilia have children?
Yes, there is nothing stopping a person with hemophilia from having children. There are several concerns a person with hemophilia should be aware of though when the time comes to have children. The first, and most obvious would be the chance for blood loss and uncontrolled bleeding during the birthing process if the mother is the one with hemophilia. While this is something to be aware of, it is also something that can be easily prepared for and overcome. In this situation, the chances of having sons and daughter who inherit the traits for hemophilia is very likely. If the mother had the genes for hemophilia on both X chromosomes, all of her children will inherit the trait (daughters may or may not be symptomatic while all sons will be). If the mother only had the trait on one of her two X chromosomes, then there is a 50% each child born would receive the trait. Since the trait for hemophilia is located on the X chromosome, and males have only one of these X chromosomes, all daughters of a male with hemophilia will receive the genes for hemophilia from him while any sons he has will not receive the gene.
Why are males more likely to have a sex-liked trait than females?
Males have only one X chromosome. This means that only one copy of the sex-linked trait has to be passed toa male inorder for him to have the trait. If the mother is a carrier her male offspring have a 50% chance of inheriting and having the affected phenotype. Her daughters, will have a 50% chance of being carriers of the trait and could only be affected if the father is affected,
Can your wife stop you from seeing your children prior to a divorce?
Not if the father is doing his fatherly duties for the children, and causing the children no harm or pain. But if he is then yes, also if she sees the father unfit and suspects harm is being done in which case it should be taken to court.
Why did Mother Teresa only help children?
She helped people of all ages, not just children.
