Phenotype: Function, Tasks, Role & Diseases

The phenotype is the outwardly visible appearance of an organism with its various characteristics. Both genetic makeup (genotype) and environment influence the expression of the phenotype. What is the phenotype? The phenotype is the outwardly visible appearance of an organism with its various characteristics. The visible expressions of an organism, but also the behavior and … Phenotype: Function, Tasks, Role & Diseases

Phenotypic Variation: Function, Role & Diseases

Phenotypic variation describes different trait expressions of individuals with the same genotype. The principle was popularized by the evolutionary biologist Darwin. Diseases such as sickle cell anemia are based on phenotypic variation and were originally associated with an evolutionary advantage. What is phenotypic variation? By phenotypic variation, biology refers to the different trait expressions between … Phenotypic Variation: Function, Role & Diseases

Phenotypic Changes: Function, Task & Diseases

The appearance of an organism is called its phenotype. In this context, the phenotype is shaped both genetically and by the environment. Natural phenotypic changes in an organism are usually caused by environmental factors. What is phenotypic change? Natural phenotypic changes to an organism are usually caused by environmental factors. Phenotypic changes can occur in … Phenotypic Changes: Function, Task & Diseases

EEC Syndrome: Causes, Symptoms & Treatment

EEC syndrome is a rare condition that is present at birth. The abbreviation stands for the terms ectrodactyly, ectodermal dysplasia and cleft (English name for cleft lip and palate). Thus, the disease term summarizes the three most important symptoms of EEC syndrome. Patients suffer from a cleft hand or foot and defects of ectodermal dysplasia. … EEC Syndrome: Causes, Symptoms & Treatment

Gene Expression: Function, Tasks, Role & Diseases

Gene expression refers to the expression and development of a genetically predisposed characteristic of a living being. This is contrasted with genetic information that is not expressed and can only be detected by DNA analysis. What is gene expression? Gene expression refers to the expression and development of a genetically predisposed trait of a living … Gene Expression: Function, Tasks, Role & Diseases

Reaction Standard: Function, Tasks, Role & Diseases

The reaction norm corresponds to the genetically designed range of possible variations of two phenotypes of the same genetic material. The ultimate trait expression within this predetermined bandwidth depends on the external environmental influences in each case. The range of modification also plays a role in the context of genetic predispositions to disease, which need … Reaction Standard: Function, Tasks, Role & Diseases

Breast cancer – What does BRCA mean? | Genetic test – When is it useful?

Breast cancer – What does BRCA mean? Breast cancer is a disease that is usually multifactorial in origin. This means that many internal and external circumstances contribute to the coincidence of breast cancer development. Angelina Jolie is one of the best known examples where a genetic mutation increases the risk of breast cancer. She had … Breast cancer – What does BRCA mean? | Genetic test – When is it useful?

Genetic test for colorectal cancer | Genetic test – When is it useful?

Genetic test for colorectal cancer Colorectal cancer is also favored by many influenceable internal and external influences and genetic constellations. In colorectal cancer, diet, behavior and external circumstances play a much greater role than in breast cancer. Only about 5% of all colorectal cancers can be attributed to a genetic change.If close relatives of the … Genetic test for colorectal cancer | Genetic test – When is it useful?

Determine parentage and origin | Genetic test – When is it useful?

Determine parentage and origin Parentage is the term used to describe the range of relatives whose genetic make-up one carries. Certain genes are located at different sites in the genome and can therefore be subject to different hereditary traits. If there is a defective gene in the family history, it is possible to calculate the … Determine parentage and origin | Genetic test – When is it useful?
