a woman who is heterozygous for the gene
an autosomal recessive disorder, meaning that having an affected offspring requires both unaffected parents to be carriers. Parents who carry the disorder will have a 25% risk of having an affected offspring in subsequent pregnancies.
autosomal dominant is only when one allele is messed upautosomal recessive is when you give the disease to your child 50/50 chance.Not true.... 50/50 when its Autosomal Dominant(see below)Recessive InheritanceBoth parents carry a normal gene (N), and a faulty, recessive, gene (n). The parents, although carriers, are unaffected by the faulty gene. Their offspring are affected, not affected, or carriers. This type of inheritance was first shown by Mendel.Dominant InheritanceOne parent has a single, faulty dominant gene (D), which overpowers its normal counterpart (d), affecting that parent. When the affected parent mates with an unaffected and non-carrier mate (dd), the offspring are either affected or not affected, but they are not carriers.
What kind of diseases are the most common genetic diseases? (For example, those in which both parents may be carriers of the disease without knowing it because they don't actually have the disease.)
If the older generation has a disease or sth harmful, it can be passed down to the newer generations, hence causing the young to have that particular disease or abnormality.
There is some correlation between Crohn's disease and genetic but so far there is no definitive answer. Family history often shows others in the family of a patient have had some form of bowel disease. There is a great chance of a child of a Crohn's patient developing the disease later in life but the disease seems to be able to skip generations.
The disease is recessive, requiring both parents to carry the allele for the disease to be found in the offspring. If one parent has it, the offspring can also be a carrier, but it will be recessive, and the offspring will have normal RBC (red blood cells)
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
Althought the diabetes skipped many generations in my family, it was apparently a recessive trait because the newborn was diagnosed with the disease.
cystic fibrosis
As long as a persons genotype consists of at least one recessive gene, they can pass it on to offspring to give them the disease, which makes them a carrier. Since this persons genes are both recessive, it is definite that they will pass on the recessive gene.

Yes. They can pass it on to their offspring.
Wilson's disease is recessive

Because as they are homozygous recessive they are only lethal when a person inherits an allele from both parents, meaning that each parent must be heterozygous carriers of the gene, and even then it's only a 1 in 4 chance that the offspring will be homozygous recessive and therefore it's unlikely they will die. And if they do not die then the will survive to likely pass on the gene.
