Want this question answered?
Yes because most diseases or disorders are recessive and therefore there can be carriers that are normal.
Yes. They can pass it on to their offspring.
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
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.)
Most peroxisomal disorders are inherited autosomal recessive diseases, with X-ALD as an exception. They occur in all countries, among all races and ethnic groups. They are extremely rare.
Recessive Autosomal
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
They are caused by the genes that we inherit from our parents. Genes govern how our body is run. Cystic fibrosis is caused by a recessive alle. This means that both parents must be carriers of the alle responsible for cystic fibrosis. The parents don't have to have the condition themselves; they can be just carriers of the one alle that makes up the condition.
recessive autosomal
The diseases sickle cell anemia and thalassemia, both of which are inherited blood disorders caused by recessive genes. The child must get the recessive gene from both of their parents to have the disease. If the child only gets the recessive gene from one parent, they will be a healthy carrier.
