What is the probability Two individuals with autosomal recessive trait will have a child with the same trait?
If they are expressing the trait, 100%, as their genotypes would be,
rr X rr
If they both carry the trait and it is dominated, Rr X Rr, then the probability would be,
25% of their child expressing the trait.

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.
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.
Is Bassen-Kornzweig syndrome inherited?
Bassen-Kornzweig syndrome is inherited as an autosomal recessive disorder, which means that parents of affected individuals are themselves unaffected carriers, and that they have a 25% risk of having an affected child.
What are the specific names of autosomal chromosomes like sex chromosomes?
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
What are autosomal recessive diseases?
both parents contribute genetic material to their offspring, each child carries two copies of almost every gene, one from each parent. For some diseases to occur, both copies must be flawed. Such diseases are called autosomal recessive diseases
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.

If the parents are not affected and the child is affected what is the inheritance pattern?
If the parents are unaffected and the child is affected, it may suggest an autosomal recessive inheritance pattern. This means that both parents are carriers of a recessive gene mutation, which is expressed in the affected child. Each parent has one normal and one mutated copy of the gene, leading to a 25% chance of the child inheriting both mutated copies.
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.
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 the chance that their child will be a carrier of the disease if both parents suffer from the disease?
If they are expressing the trait, 100%, as their genotypes would be, rr X rr If they both carry the trait and it is dominated, Rr X Rr, then the probability would be, 25% of their child expressing the trait.
How is usher syndrome inherited?
Usher syndrome is inherited as an autosomal recessive trait. The term autosomal means that the mutated gene is not located on either of the chromosomes that determine a person's sex; in other words, both males and females can have the disorder and can pass along the disorder to a child. The word recessive means that to have Usher syndrome, an individual must receive a mutated form of the Usher syndrome gene from each parent. If a child has a mutation in one Usher syndrome gene but the other gene is normal, he or she is predicted to have normal vision and hearing. Individuals with a mutation in a gene that can cause an autosomal recessive disorder are called carriers, because they "carry" the gene with a mutation but show no symptoms of the disorder. If both parents are carriers of a mutated gene for Usher syndrome, they will have a one-in-four chance of having a child with Usher syndrome with each birth.
If both heterozygous parents are carriers of a recessive allele for phenylketonuria the probability that a given child of these parents will have PKU is?
The probability that a given child will have PKU is 25%. This is because both parents are carriers of the recessive allele (heterozygous), so there is a 25% chance that they will each pass on the recessive allele, resulting in the child having PKU.
