Recessive genetic disorder??
Question: Definition?
Answers: Please do not quote my answers... it has been a while since AP Bio!! Recesive genetic disorders just mean that both parents have to be carriers of a disease for a child to have it!! If i am not mistaken, Cystic Fibrosis is recessive. My friend has it... both of her parents had the trait, but since it is recessive they do not have the active disease. HER twin BROTHER (fraternal, not identical) does not have the diease, but she does. He is also a carrier. If both parents have the trait for a recessive disorder, their offspring have 75% chance of being carriers, 25% of having the disease. Hope I helped some?!

It's believed to be porphyria - the malady that affected poor King George III - but nowadays they can test for it at birth and administer an appropriate medication to stop it developing.

Still studying the genetic link to angelman's syndrome. From the research I have done, and who knows how much information on the internet is correct but I believe it is a sex-linked gene.
dominate traits can be expressed in the heterozygous gene state. This means if you have one dominant and one recessive gene the dominant will prevail. ie one blue and one brown, brown will prevail.
the genes of your parents.
Let
R= Dominant trait
r= Recessive trait
Homozygous dominant= RR
Homozygous recessive= rr
Heterozygous= Rr
Heterozygous individuals will have both traits, but its ph

Polio is not genetic.
To date only dominant genes were linked to Alzheimer's, but there is new evidence, that a recessive gene, may play a role in the development of Alzheimer's.

Congenital ptosis may occur through autosomal dominant inheritance. Common familial occurrences suggest that genetic or chromosomal defects are likely.
Hi, I don't think anyone knows at this point in time. Currently the thought is that there is a genetic component with perhaps an environmental trigger. Do a search for Parkinson's there are probably h
I think it's recessive alleles. Both parents must be a carrier.
