Understanding Genetic Disorders
Introduction to genetics
Genetics is the study of inherited traits and how they are passed down from generation to generation. It involves the understanding of genes, which are segments of DNA that carry the instructions for creating and functioning of proteins in the body. Genetic disorders occur when there are abnormalities in these genes, leading to various health conditions.
Phenotypes and genotypes
In genetics, phenotypes refer to the physical or observable characteristics that result from an individual’s genetic makeup, known as their genotype. Genotypes determine the traits that individuals inherit, such as eye color, height, and susceptibility to certain diseases.
Most common genetic disorders
Numerous genetic disorders exist, each with its own set of symptoms and inheritance patterns. Some common genetic disorders include Down syndrome, cystic fibrosis, sickle cell disease, Huntington’s disease, and muscular dystrophy. These disorders can vary in severity, with some causing mild symptoms while others can be life-threatening.
Probability of inheriting genetic disorders
The probability of inheriting a genetic disorder depends on various factors, including the type of disorder and its mode of inheritance. Some genetic disorders follow a recessive pattern, where both parents must carry and pass on the abnormal gene for the disorder to appear in the offspring. In other cases, genetic disorders may have an autosomal dominant pattern, where only one parent needs to pass on the abnormal gene for the disorder to manifest in the child. Genetic counselors can assist individuals in understanding the probabilities and risks associated with specific genetic disorders based on their family medical tree.
How to Create a Family Medical Tree
Researching family medical history
Creating an accurate family medical tree requires thorough research into the health history of relatives.
