Which is an example of how genetics affect health?
Genetic variations can have large or small effects on the likelihood of developing a particular disease. For example, certain mutations in the BRCA1 or BRCA2 genes greatly increase a person’s risk of developing breast cancer and ovarian cancer.
What are some unique ways that genetics is used in the field of medicine and health?
Genetic tests are used to diagnose certain disorders (for example, hemochromatosis and chromosome disorders such as Down syndrome and Turner syndrome). Genetics is also increasing the ability to predict what disorders a person is likely to develop.
What are five examples of genetic factors?
What You Need to Know About 5 Most Common Genetic Disorders
- Down Syndrome. Typically, the nucleus of an individual cell contains 23 pairs of chromosomes, but Down syndrome occurs when the 21st chromosome is copied an extra time in all or some cells.
- Cystic Fibrosis.
- Tay-Sachs disease.
- Sickle Cell Anemia.

How can the understanding of genetics be used in medicine?
Genetics will be important not only to understanding the cause of a disease, but also to recognizing the manner in which an individual responds to particular therapies. Drug metabolism is itself under genetic control, and susceptibility to side effects in some cases is governed by genetic predispositions.
What is genetics and its importance?
Genetics can help us to understand why people look the way they do and why some people are more prone to certain diseases than others. Genetics can help health-care professionals to identify certain conditions in babies before they are born using techniques such as prenatal testing.
What are the uses of genetics?
How is heritability determined?
Heritability is expressed as H2 = Vg/Vp, where H is the heritability estimate, Vg the variation in genotype, and Vp the variation in phenotype.
Is having dimples dominant or recessive?
Dimples—indentations on the cheeks—tend to occur in families, and this trait is assumed to be inherited. Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples.
Can dimples be created?
Though a dimple is a facial feature one gets genetically, there are many ways you can actually get a dimple without undergoing a surgery. Yes, even those who are born without a dimple can mimic this facial feature through different ways. We share with you ways to successfully mimic the appearance of a dimple.
Are dimples rare?
Around 20-30% of the world’s population has dimples, which makes them quite rare. In many cultures, dimples are a sign of beauty, youth, and luck.
Can dimples go away?
Yes, it is possible for your dimples to go away, especially if your parents do not have dimples. At times, children do not have dimples at birth but develop them later in childhood. In some people, dimples last only until adolescence or young adulthood and later fade away once the muscle grows fully.
Are smile lines dimples?
“Some people have dimples that they mistake as smile lines, but the lines are really part of their dimple complex—especially if it seems like you have double parentheses right near the angle of your mouth.” Which, she explains to us, is much harder to correct.
Are shoulder dimples rare?
There was no restriction of movement of the shoulders. Such dimples did not occur in other family members. Symmetrical dimples of the skin overlying the acromial processes of the scapulae are so called bi-acromial dimples. These dimples are found infrequently, and are a solitary finding in most cases.
How do you get rid of shoulder dimples?
What You’ll Need: The water cooler. Whether you call them ‘hanger bumps,’ ‘shoulder horns’ or ‘sweater nipples’ (ew), get rid of them quickly by wetting your fingers and then vigorously rubbing them over the bump. The wet fibers will eventually and mold to your shoulders once they dry (this can take up to 10 minutes).
How do you get dimples?
Movement of the skin over the double zygomaticus major muscle when you smile causes the dimple to form. Because cheek dimples can result from a muscular variation that occurs during fetal development, they’re sometimes mistakenly referred to as a birth defect.
How rare is a cleft chin?
The frequency of cleft chin varies widely among different populations; Indian populations range from 4 to 71 percent cleft chin (Bhanu and Malhotra (1972). Günther (1939) recorded cleft chins in 9.6 percent of German men and 4.5 percent of German women.
