Haircolor ranges from platinum blond to ebony, due to levels of pigments produced by specialized cells called melanocytes. Those with dark hair have cells that produce a pigment called eumelanin, and those with blond or red hair have cells that produce pheomelanin. The relative ratio of eumelanin to...

Geneticdiseases and disorders are the result of anomalies in a gene or an entire part of the chromosome of an individual.
Genes are segments of DNA that determine specific traits, such as eye or haircolor. You have more than 20,000 genes. You have two copies of each gene — one inherited from each of your parents.

Geneticdiseases are classified by type: chromosomal abnormalities, single gene defects, problems caused by exposure to certain substances, or a
Geneticdisorders are caused by the mutation of a gene. This genetic mutation can be passed from parents to a child at the time of conception.
Geneticdisorders are caused by changes in the structure or number of the chromosomes or in the DNA. Genetic problems arise due to different reasons
A geneticdisorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Geneticdisorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of...
A geneticdisorder is a disease that is caused by a change or mutation in an individual’s DNA. There are three types of geneticdisorders Single-genedisorders, Chromosomal disorders, and Multifactorial disorders. Types All Articles.
Uncombable hair syndrome (UHS) is a rare disorder of the hair shaft of the scalp. It is usually characterized by silvery-blond or straw-coloredhair that is disorderly; stands out from the scalp
Such disorders are known as multifactorial geneticdisorders. Principles of genetic inheritance.
Geneticdisorders are diseases whose root cause is a mutation in the genome.
Many health conditions and diseases are also genetic. Genes may also influence some behavioural characteristics, such as intelligence and natural talents.
Distinctive haircoloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition.
Covers human geneticdisorders, includes both dominant and recessive disorders.
GeneticDisorders (National Human Genome Research Institute). Genetics Home Reference (National Library of Medicine).
Geneticdisorders are diseases due to abnormality in one’s DNA (in medical terms, Deoxyribonucleic acid). These abnormalities may be associated with just a single or multiple genes and chromosomes. Common cases are already found from before birth.

Some geneticdisorders are hereditary, meaning the genetic change is passed on from their parents. Other genetic changes can happen for the first time in the baby. Parents can carry a change in a gene or a chromosome without realizing it, as it may not cause them any health problems.
Geneticdisorders in children are the diseases that are inherited and passed down in every family generation and are caused by different gene variation
What is a geneticdisease or disorder? Learn from a list of geneticdiseases that are caused by abnormalities in an individual's genome. There are four main types of genetic inheritance, single, multifactorial, chromosome abnormalities, and mitochondrial inheritance. Genetic testing is available...
This concept applies to disorders as well. In most geneticdisorders, a nonfunctional or partially nonfunctional protein is created instead of a healthy protein. If both a healthy gene and an unhealthy gene is present, usually there is enough of the healthy protein also being created to not affect the...
