What kind of diseases are the most common genetic diseases For example those in which both parents may be carriers of the disease without knowing it because they don't actually have the disease?

Why might parents decide to have genetic testing?
Parents might decide to have genetic testing to determine if either or both of them carry certain genetic traits that could be passed on to their offspring. Some genetic traits will lead to severe birth defects or problematic diseases that could severely impact the quality of their children's lives. If they are indeed carriers of certain traits, they may choose to avoid having children or choose adoption as an alternative. In this way, they can eliminate their particular genetic line and avoid passing the trait on to the next generation.
Is it true that you will definitely inherit a genetic disease if both your parents show any sign of the disease?
IT depends if both parents have it on their genes (X and Y) as Dominant or Recessive, If one of them is dominant, you better expect to get it unless the other parent has a DOminant Counter-Gene
How is Sandoff disease passed on in families?
an autosomal recessive disorder, meaning that having an affected offspring requires both unaffected parents to be carriers. Parents who carry the disorder will have a 25% risk of having an affected offspring in subsequent pregnancies.
Difference between an autosomal recessive disorder and an autosomal dominant disorder?
autosomal dominant is only when one allele is messed upautosomal recessive is when you give the disease to your child 50/50 chance.Not true.... 50/50 when its Autosomal Dominant(see below)Recessive InheritanceBoth parents carry a normal gene (N), and a faulty, recessive, gene (n). The parents, although carriers, are unaffected by the faulty gene. Their offspring are affected, not affected, or carriers. This type of inheritance was first shown by Mendel.Dominant InheritanceOne parent has a single, faulty dominant gene (D), which overpowers its normal counterpart (d), affecting that parent. When the affected parent mates with an unaffected and non-carrier mate (dd), the offspring are either affected or not affected, but they are not carriers.
Sickle-cell anemia is a disease passed by autosomal recessive inheritance. What is the likelihood that a person who has two parents with the disease will be a carrier of the defective gene?
If both parents have sickle-cell anemia, their child will inherit one copy of the defective gene from each parent, making them a carrier. Thus, the likelihood that a person who has two parents with the disease will be a carrier of the defective gene is 100%.
What is a likelihood that a person who has two parents with the disease will be a carrier of the defective gene?
100%
What if Sickle cell anemia is a disease passed by autosomal recessive inheritance.what is the likelihood that a person who has two parents with the disease will be a carrier or the defective gene?
If sickle cell anemia is inherited in an autosomal recessive manner, a person with two parents who both have the disease will inherit two copies of the defective gene. Consequently, this individual cannot be a carrier; they will be affected by the disease. In this case, the likelihood of being a carrier is 0%, as they will have the genotype that expresses the disease rather than one that carries it without symptoms.
Is sickle cell anemia an deficiency disease?
The sickle cell anaemia is not a deficiency disease. It is a hereditary disease caused by defective gene in both the parents.
How many parents need to be a carrier of the disease?
Please put the NAME of the disease in your question, so that the question can be answered.
Gaucher disease is caused by what genetic disorder?
Gaucher disease has a recessive pattern of inheritance, meaning that a person must inherit a copy of the defective gene from both parents in order to have the disease.
What chances does an offspring have of getting Gaucher Disease?
It depends on whether your parents are carriers or not. If they are NN (or normal normal) and they have sex with someone who is Nn (or normal gauchers) than using a punnet square the chances of them becoming a carrier are 50 50. If your parents are both carriers ie. Nn Nn then the chances of them becoming a carrier are 50% and them having the disease is 25%. If your parents are nn Nn then the chances of them becoming a carrier is 50% and the chances of them having the disease is 50% so they will either be a carrier or have the disease either way. If your parents are nn NN then there is a 100% chance of them being a carrier. You can figure this out by looking at your family tree and seeing who had the disease before you in your family. This is only very basic Mendelian genetics so i would consult a doctor for a more legitimate answer.
To be a cystic fibrosis carrier do your parents have to have a cystics fibrosis gene?
Yes, since the disease is a recessive inherted trait BOTH parents must carry the gene but will not have the disease itself. Approximately 30,000 people in the United States have cystic fibrosis. An additional ten million more-or about one in every 31 Americans-are carriers of the defective CF gene, but do not have the disease. The disease is most common in Caucasians, but it can affect all races.
How is a carrier different from a person who has genetic disorder?
A carrier means that you have the gene for the disorder, but because the gene is recessive (meaning that it only shows when you have two recessive genes) and you obviously have a dominant gene as well, you won't show the disorder. Someone who actually has the disorder has two recessive genes. D = dominant gene r = recessive gene Dr = carrier, no signs rD = carrier, no signs DD = not a carrier, no signs rr = has the disorder
Can a person be a carrier for a genetic disease if neither or only one of their parents are carriers?
Yes, it is possible for a person to be a carrier for a genetic disease even if neither of their parents are carriers. This can occur if the person has a new mutation in the gene associated with the disease. Carriers have one copy of the mutated gene, which they can pass on to their children.
Can a mother with a rare gentic disease pass it to her son?
A female who carries a defective recessive gene on one of her two X chromosomes has a 50% chance of passing the defective gene to her sons who will develop Fabry's disease associated with the defective gene.
Why do 25 percent of cf carrier s children get cystic fibrosis?
Cystic fibrosis (CF) is an autosomal recessive genetic disorder, meaning that a child must inherit two copies of the defective CFTR gene—one from each parent—to develop the disease. When both parents are carriers of the CF gene mutation, there is a 25 percent chance with each pregnancy that their child will inherit both defective genes, resulting in cystic fibrosis. Additionally, there is a 50 percent chance the child will be a carrier (inheriting one defective gene) and a 25 percent chance the child will inherit two normal genes.
