WebbGenes are the molecular unit of heredity. In an organism, the gene sequence may occur in one or more forms, and these alternate forms of the same gene are called alleles. Any type of change that is observed in the sequence of these alleles or in the structure of the genes gives rise to genetic variation in the genome of that organism. WebbA number of genetic disorders are caused when an individual inherits two recessive alleles for a single-gene trait. Recessive genetic disorders include albinism, cystic fibrosis, galactosemia, phenylketonuria (PKU), and Tay–Sachs disease.
