What is the probability of producing a normal child by two parents who are carriers for an autosomal recessive disorder?

75%.
Explanation: if both parents are carriers than their Gametes would be Dd x Dd, resulting in DD (1/4), Dd (2/4), and dd(1/4), meaning that there is a 25% chance that they will have a child that has the disorder.
DD = A normal child that lacks the recessive gene, therefore not a carrier
Dd = A normal child that carries the recessive gene
dd = A child with the disorder + carries the gene, hence the child's future offspring will carry it as well.

Is sickle cell anemia recessive or dominant?
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
Is sickle cell an dominant or recessive?
Sickle cell anemia is an autosomal recessive disorder. It can result from two carriers having a child together.
Does FAP follow a recessive or dominant inheritance pattern and why?
FAP follows both an autosomal recessive and autosomal dominant pattern depending on which gene you inherit the disease from. If inherited through the APC gene, which is most common, it is autosomal gdthe disease. If inherited through the MUTYH gene it is autosomal recessive, meaning that both parents were carriers of the disease or they both were living with the disease.
Is prenatal testing done for Von Willebrand disease?
If one parent has been diagnosed with an autosomal dominant form of VWD or both parents are carriers for an autosomal recessive form of VWD, then prenatal testing can be considered
What is the probability that each child born to two carriers of a recessive disorder allele will have the disorder?
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
Who can be carrier of autosomal disorder?
females
Is albinism heterozygous or homozygous?
genetically albinism is an autosomal recessive gene which in fact gives the child a 25% chance of inheriting the gene if both parents are carriers
What is automasal trait?
With an autosomal recessive inheritance pattern, a person needs to have 2 copies of a gene change to have the condition. In most cases, people with an autosomal recessive condition get one gene change from the mother and one gene change from the father.The parents of a person with an autosomal recessive condition may not have the condition themselves, since each parent only needs to have one copy of the gene change. People with one copy of the gene change are called carriers, who do not have the condition, but are more likely to have children with the condition. Other family members (uncles, aunts, brothers, cousins, etc) may also be carriers.
Is alkaptonuria caused by a recessive or dominant allele?
Phenylketonuria is an autosomal recessive genetic disorder. The enzyme phenylalanine hydroxylase is necessary to metabolize phenylalanie, but when this enzyme doesnt work, phenylaline accumulates and is detected in the urine. The disease is detected during pregnancy, and if treated right away the newborn can develop normally. However, if left untreated, the brain will not develop properly.
Compare the inheritance of Huntingtons disease with the inheritance of sickle cell anemia?
Huntingtons disease is Autosomal dominant, i.e. a 50% chance of inheritance if one parent has the gene. Where as sickle cell anemia is autosomal recessive. This gives a 25% chance of inheritance if both parents are carriers.
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?

What are the inheritance patterns for SMA?
Inheritance pattern for most forms of SMA is autosomal recessive, meaning that both parents are carriers of the disorder, and the chance of having a child affected with the disorder is 25% with each pregnancy.
