Find practice Genetic Disorders Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Genetic Disorders.

Generally, genetic disorders are conditions that arise through alterations in DNA within the body; that is, such alterations affect how genes function, thus leading to several health issues. Genetic disorders can be hereditarily acquired or formed spontaneously resulting from factors of mutation. These could be categorized under single-gene disorders, chromosomal disorders, and multifactorial disorders.

Single-gene disorders include disorders related to a single gene. Such disorders include among others cystic fibrosis, sickle cell anemia, and Huntington’s disease. It manifests depending on the type of gene involved, either as an autosomal dominant or autosomal recessive. In this case, cystic fibrosis is manifested as an autosomal recessive disorder because the person has inherited two defective copies of the gene.

A chromosomal disorder is a condition where there is an imbalance or irregular structure of chromosomes. Down syndrome is one such chromosomal disorder where there is an extra copy of chromosome 21. Generally, it causes developmental and intellectual disabilities.

Multifactorial disorders, such as heart disease and diabetes, arise from genetic and environmental factors. As such, multifactorial disorders have more complex etiology due to their interaction with multiplex genes and lifestyle factors.

Advanced diagnosis and treatment of genetic disorders because there has been great improvement in genetic testing and counseling. Techniques including genomic sequencing and carrier screening are being used to identify at-risk people to give them options for early intervention and tailored treatments.
