Introduction Genetic diseases are caused by any abnormality that might occur in an individual’s genome. Some genetic disorders are transmitted or inherited from parents to their offspring while others are caused by acquired mutation or changes in an already existing gene. Mutations can take place randomly or due to some environmental factors. There are different modes of genetic disorders that include single gene and multifactorial inheritance, chromosome abnormalities, and mitochondrial inheritance

There are numerous genetic disorders that our society can suffer from but usually are very rare and affect only one out of thousands or millions. When we think of genetic disorders, the term genetic allows to think about genes – a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring – therefore, making us believe that because a certain disorder or condition is considered genetic, it must mean that

It causes uncontrolled body movements, emotional unstableness, and loss of cognition. The most common form of this disorder is Adult-onset Huntington’s

the thickened tail. The definite cause of the feline osteochondrodysplasia is the single autosomal dominant trait, designated as Fd, which determines the ear folding of the cat(Todd NB 2:64-65). In the study by Robinson R "Normal genetics, genetic disorders, developmental anomalies and breeding programmes," most of the cat with osteochondrodysplasia was homozygous for this trait, which means both of
