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.
Why can an individual be a carrier but not have that disorder?
Yes because most diseases or disorders are recessive and therefore there can be carriers that are normal.
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
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.
Is it true carriers of genetic diseases who do not have the disease themselves have recessive genes for the disorder?
Yes. They can pass it on to their offspring.
What is the probability a woman heterozygous for an x-linked trait will have a son with a genetic disorder if the genetic disorder is recessive?
It will be all about the gains and shreins
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.

Who can be carrier of autosomal disorder?
females
If a genetic disorder is carried on a recessive gene which if any will have the disorder?
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Do parents suffer from a recessive disorder passed to their children?
Parents who carry a recessive disorder gene have a 25% chance of passing the disorder to their children. They may not necessarily suffer from the disorder themselves, as carriers typically do not show symptoms. However, they can still transmit the gene to their offspring, who may then inherit the disorder.
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.
Can a person be a carrier for a dominant genetic disorder?
Anyone can be a carrier of a recessive genetic disorder (as long as it is not associated with the sex chromosomes) no matter what their gender since "carrier" refers to an individual that is heterozygous for the recessive allele and therefore phenotypically normal. Specifically, sexlinked genetic disorders can be "carried" by a heterozygous female but males (having only one X chromosome) cannot. Males will either be free of the defective gene or be affected.
