Pleiotropy describes the genetic effect of a single gene on multiple phenotypic traits. The underlying mechanism is that the gene codes for a product that is for example used by various cells, or has a signalling function on various targets. A classic example of pleiotropy is the human disease PKU (phenylketonuria). This disease can cause mental retardation and reduced hair and skin pigmentation, and can be caused by any of a large number of mutations in a single gene that codes for an enzyme (phenylalanine hydroxylase) that converts the amino acid phenylalanine to tyrosine, another amino acid. Depending on the mutation involved, this results in reduced or zero conversion of phenylalanine to tyrosine, and phenylalanine concentrations increase to toxic levels, causing damage at several locations in the body. PKU is totally benign if a diet free from phenylalanine is maintained.
Sickle cell anemia is not sex linked.
Hemoglobin SS disease (Hb SS)
Yes, sickle cell anemia is a type of poikilocytosis, which is a condition characterized by the presence of abnormally shaped red blood cells in the bloodstream. In sickle cell anemia, the red blood cells are crescent or sickle-shaped due to a genetic mutation in the hemoglobin protein.
Spherocytosis
polygenic inheritance . doug says " squirrel". hes a fat dog.
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
No
Yes, sickle cell anemia is an example of codominance in genetics.
Genetic disorder
well no cancer can not be cured by sickle celled anemia because sickle cell is the abnormalty of the shape of the cell.
You get Sickle-Cell Anemia by Birth,it is a genetic disorder.
Yes. This answer is TRUE.
Yes, Sickle Cell Anemia is in fact a genetic disorder.
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
sickle cell anemia
Sickle cell anemia -yes it is hereditary
