When a genetic disorder is recessive, that means that two copies of the gene are necessary to have the trait or disorder. One is inherited from the mother, and one from the father. Disorders of this type include: cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
What else can I help you with?
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.
Is progressive retina atrophy a recessive or dominant genetic disorder?
Progressive Retina Atrophy is a dominant genetic disorder.
Is aspergers a dominant or a recessive?
No. Autism is a neurodevelopmental disorder
A example of a homosygous genetic disorder?
Cystic Fibrosis is a recessive homozygous genetic disease
If you were a carrier of one allele for a certain recessive disorder how could genetic counseling help you prepare for the future?
Well, genetic counseling usually tells someone the consequences of their recessive disorder.
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?
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.
Is cystic fibrosis a dominant or co-dominant disorder?
It is autosomal recessive and it is not a disorder! Cystic Fibrosis is a disease.
What type of genetic disorder is PKU?
PKU is described as an inherited, autosomal recessive disorder.
Is galactosemia sex-linked?
No, it is a genetic metabolic disorder.
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 a heterozygous indivisual who doesnt show a reccesive genetic disorder but who can pass a reccesive allele on to their offspring is called what?
The individual is called a carrier. This means they carry a recessive allele for a genetic disorder, but they do not exhibit symptoms of the disorder themselves. However, they can pass on the recessive allele to their offspring.
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
