Quizplus · Accepted Answer

Huntington's disease is caused by a dominant allele, meaning that individuals who inherit just one copy of the allele will develop the disease. This distinguishes it from disorders like sickle-cell disease and phenylketonuria, which are caused by recessive alleles and require two copies for an individual to be affected. Turner's syndrome is a chromosomal disorder caused by missing or incomplete sex chromosomes and is not inherited in a dominant or recessive pattern.
