Is alkaptonuria a dominant or recessive disorder?
Alkaptonuria (black urine disease, black bone disease) is a rare inherited genetic disorder in which the body cannot process the amino acids phenylalanine and tyrosine, which occur in protein.
Alkaptonuria is RECESSIVE IN NATURE
Alkaptonuria is caused by mutation of the homogentisate 1,2-dioxygenase (HGD) gene. This mutation is inherited as an autosomal recessive trait. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from the father and the mother.
