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.

∙ 7y agoYes. Phenylketoneuria is the genetic disorder. It is autosomal recessive genetic disorder. If both the parents are carriers of the genes, then there are 25% chances of you getting the disease. 50% chances of you becoming the carrier. 25% chances of neither getting the disease nor the carrier state.

Autosomal dominant allele
Is hunters disease dominant or recessive?
Huntingdons chorea is caused by a dominant allele.
What is caused by a dominant allele located on an autosome?
The dominant allele will cause the appearance of the phenotype that this dominant allele represents...
How do dominant and recessive alleles affect an offsprings phenotype?
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.

Autosomal dominant allele
Is the allele causing huntington's disease dominant or recessive?
Huntington's disease is caused by a dominant allele
Is hunters disease dominant or recessive?
Huntingdons chorea is caused by a dominant allele.
Is it true that a defective allele always recessive and a normal allele always dominant?
No. The gene that causes Huntington's is caused by an autosomal dominant mutation, and one form of inherited Parkinson's is also caused by an autosomal dominant mutation.

Is hemophillia caused by a recessive allele?
yes
Being a carrier of sickle cell anemia means?
sickle cell anemia is caused by a recessive allele. so for it to affect someone, it means that the person must have received both recessive alleles from their parents. Being a carrier means that you have the recessive allele from one of your parents, but you have a normal dominant allele from the other parent, that means you are not affected by it but you are carrying it.
Is cystic fibrosis caused by a dominent or recessive gene?
It is caused by a recessive allele. Believe me my teacher told me.
Is adrenoleukodystrophy dominant or recessive?
This disease results from a mutation on the x-chromosome. It's recessive considering that a dominant will only cover up things that have occur, for example the damage that has occured, with something else. A recessive will continue to give latent traits. The allele in Adrenoleukodystrophy can only be caused by heredity mutation thus making it recessive.
How can a sister with the same parents have different hair colors?
Yes, this is possible. The parents may not have the same hair color as their offspring, because the offspring could have the hair color caused by a recessive allele. This allele could have been present in an ancestor, but not shown up again because its frequency is not as common as another hair color
