Genetic Diseases

Many inherited disorders in humans are controlled by a single gene. Achondroplasia is a form of dwarfism. About one out of 25,000 people has achondroplasia. The homozygous dominant genotype causes death of the embryo, and therefore only heterozygotes, individuals with a single copy of the defective allele, have this disorder. This also mean that a person with achondroplasia has a 50% chance of passing the condition on to any children. Achondroplasia is a recessive allele.

One example is Huntington's Disease. Carried on a dominant gene, it causes deterioration of the central nervous system, affecting movement, swallowing, personality, etc.

What kind of diseases are the most common genetic diseases? (For example, those in which both parents may be carriers of the disease without knowing it because they don't actually have the disease.)

# They are SO numerous: Angelman's syndrome, Huntington's Disease, Hemophilia, Turner Syndrome, Tay-Schs disease, sickle cell anemia, Praeder-Willi Syndrome, neurofibromatosis, Klinefelter syndrome, phenylketonuria, Down's Syndrome, Cystic Fibrosis, celiac disease, color blindness, cri du chat, Canavan disease, Duchenne muscular distrophy, Charcot-Marie Tooth Disease, 22q11.2 deletion syndrome, achondroplasia and many, many more.

A genetic disorder is something an individual is born with, and results from a problem within their genetic material. This means they have inherited the disease or disorder from their Mother or Father. You cannot inherit an infectious disease, you acquire it during your lifetime from a germ, such as a virus or a bacterium. You can also recover from an infectious disease, whereas you will always suffer from a genetic disorder if you inherit one.

You must make sure he has all the symptoms. People with klinefelter haven't just got small testes; there are some things you can see on the outside. These are some of the symptoms:

* They have a rather tall, thin body

* They aren't to muscular

* They have small testicles

Tulips exhibit different colors due to variations in their genetic makeup, which influences the types and amounts of pigments produced in their petals. The primary pigments responsible for tulip colors include anthocyanins, carotenoids, and betalains, each contributing to shades of red, yellow, and purple. Additionally, selective breeding by horticulturists has enhanced and diversified the color range available, resulting in the vibrant and varied tulip varieties we see today. Environmental factors, such as soil composition and sunlight, can also subtly affect their coloration.

"The Guardian Angel Gene"

We know that most individuals with Williams syndrome are missing genetic material on chromosome #7 including the gene that makes the protein elastin (a protein which provides strength and elasticity to vessel walls.) It is likely that the elastin gene deletion accounts for many of the physical features of Williams syndrome. Some medical and developmental problems are probably caused by deletions of additional genetic material near the elastin gene on chromosome #7. The extent of these deletions may vary among individuals. If a patient has 2 copies of the elastin gene (one on each of their chromosomes #7), they probably do not have WS. If the individual only has one copy, the diagnosis of WS will be confirmed. Virtually all (98-99%) persons with typical features of WS will have a deletion of the elastin gene. In more technical terms: Williams syndrome is the result of a deletion of the 7q11.23 region of chromosome #7 containing the elastin gene and is believed to be a contiguous gene syndrome. Diagnosis of Williams syndrome is confirmed by dual colour FISH using a specific probe and a control probe.

About 1 in 10000 clovers are four leaf clovers and it is still debated whether the cause is environmental conditions, genetic, or some combination.

There has been genetic engineering efforts made to increase the production of four leaf clovers for the purpose of selling more "good luck charms".

Either way there seems to be no advantage or disadvantage to the clover plant with either three or four leaves.

Genetic anomalies where the normal compliment of chromosomes is either more or less than the expected value. In humans the most common trisomy occurs with chromosome 21 and results in Down Syndrome. Very few instances of fewer than a 2N chromosome count result in viable offspring although a child with a single X (sex chromosome) can reach term.

It is genetic.
