Patterns of Inheritance: Genetic DisordersAmna Adnan
This chapter explains the inheritance patterns of autosomal dominant, autosomal recessive, X-linked inheritance, Y-linked inheritance, and inheritance of mitochondrial disorders. The concepts of penetrance and variable expressivity are introduced to further explain that genetic disorders are rarely single-...
In humans, there are many other disorders that show multifactorial inheritance patterns, such as multiple sclerosis, diabetes, asthma,cancer, and numerousbirth defects. All of these diseases are due to a complexinteractionof genetic factors, such ascopy number variation,epistatic interactions,andmodifier...
Heredity refers to the genetic transmission of traits from parents to offspring, while inheritance encompasses both genetic traits and material assets passed down.
For example, one gene might have two alleles – one for brown eyes and one for blue eyes. Digenic inheritance can lead to a wide range of traits or conditions. For example, some cases of retinitis pigmentosa, a group of genetic disorders that cause progressive vision loss, are believed to...

Genetic Disorders Affecting Growth and Development Robert S.Sparkes,Barbara F.Crandall, inFetal-Placental Disorders, 1972 VIIIExtrachromosomal Inheritance Although most inherited traits follow patterns of chromosomal inheritance, some do not and may be attributable to extrachromosomal inheritance. Most of ...
Health or disease is shaped for all individuals by interactions between their genes and environment. Exactly how the environment changes gene expression and how this can lead to disease are being explored in a fruitful new approach to environmental health research, representative studies of which are...
Mutations in the DNA sequence of a specific gene cause a single-gene disorder, The DNA changes affect the product that the gene codes for—usually a protein—causing it to be altered or missing, Some genetic disorders are so severe that children with the
