   What is clinical genetics?

   • Clinical genetics involves the study, counselling and treatment of individuals and families with heritable disorders and disease predisposition. Diagnostic tools include standard ontologies for describing dysmorphology and traits, pedigree analysis, disease locus mapping by linkage or homozygosity, karyotyping, genome sequencing and genotyping.

   What are single hereditary factors?

   • These single hereditary factors were identified as genes. Copies of genes are transmitted through sperm and egg and guide the development of the offspring. Genes are also responsible for reproducing the distinct features of both parents that are visible in their children.

   What is autosomal dominant disorder?

   • Autosomal dominant disorder. When geneticists talk about dominant disorders, they're usually referring to those rare disorders that are caused by a spelling change in the DNA of one copy of a gene. Now because the chance of passing on the altered gene copy to each child is 50%, you typically see the disorder in each generation of the family tree.
