I'm having trouble answering 4 out of 7 questions for my genetic disease report. Can anyone help me?
*How is baldness inherited?
*How many people get baldness yearly?
*Can scientists genetically screen for baldness?
*Where is the gene on the chromosomes?
Links and/or any info you know is greatly appreciated! It is most definitely an inherited trait.
It was previously believed that baldness was inherited from a person's maternal grandfather. While there is some basis for this belief, both parents contribute to their offspring's likelihood of hair loss. Most likely, inheritance is technically "autosomal dominant with mixed penetrance" [citation needed](see 'baldness folklore' below)
There are several other kinds of baldness:
Traction alopecia is most commonly found in people with ponytails or cornrows who pull on their hair with excessive force. Wearing a hat shouldn't generally cause this, though it is a good idea to let your scalp breathe for 7 hours a day[citation needed].
Traumas such as chemotherapy, childbirth, major surgery, poisoning, and severe stress may cause a hair loss condition known as telogen effluvium.[2]
Some mycotic infections can cause massive hair loss.[3]
Alopecia areata is an autoimmune disorder also known as "spot baldness" that can result in hair loss ranging from just one location (Alopecia areata monolocularis) to every hair on the entire body (Alopecia areata universalis).
Localized or diffuse hair loss may also occurs in cicatricial alopecia (lupus erythematosus, lichen plano pilaris, folliculitis decalvans, central centrifugal cicatricial alopecia, postmenopausal frontal fibrosing alopecia, etc.). Tumours and skin outgrowths also induce localized baldness (sebaceous nevus, basal cell carcinoma, squamous cell carcinoma).
Hypothyroidism can cause hair loss, especially thinning of the outer third of the eyebrows
For more info look up "alopecia" on wikipedia.com HI!
Baldness is a genetically inherited disease...we have two copies of genes ..so it depends what combination u inherited from ur parents ..plus hormonal imbalances which moreso in man (DHT-testosterone) level change accelerating baldness.Yes we can screen but its usually not done..There are no figure but its a guess 20 % of people start going bald by 25 Hi There
Here are some ideas what causes it and to correct it.
Cause
Hair loss can occur due to low thyroid functioning, poor digestion, parasites, nutrient deficiencies such as iron or biotin, hormonal problems, aging, trauma, post-pregnancy, skin disease, diabetes, chemotherapy, and stress. All of these factors must be considered and ruled out to be sure hair loss is not part of a more serious, underlying condition.
Caution: If you begin to lose large amounts of hair suddenly and for no apparent reason, seek prompt medical attention to rule out the possibility of an underlying disease.

Natural Cures
Aromatherapy: For temporary or severe hair loss, massage lavender, rosemary, thyme, or sage essential oils directly onto the scalp.
Ayurveda: The Ayurvedic herbs ashwagandha and amla can help stimulate hair growth in cases that are not due to genetic predisposition.
Diet: Eat an organic, whole foods diet high in potato (with skins intact), green and red peppers, sprouts, and unpeeled cucumbers. Such foods are high in silica, which gives strength to hair and nails. Foods high in iron, such as some lean meats and raisins, are also important. Sea vegetables such as kelp are also good for the hair and support proper thyroid function. Be sure to check for and eliminate any foods to which you may be allergic or sensitive.
Herbs: Massage the scalp nightly with an oil made of one part rosemary oil and two parts almond oil.
Homeopathy: Sepia, Arnica, and Acidum nit. are useful homeopathic remedies.
Juice Therapy: Drink the combined juice of carrot, beet, spinach, nettle, and alfalfa, adding a bit of onion.
Lifestyle: Circulation to the scalp is important and can help prevent hair loss. Increase exercise, scalp massage, and try lying on a slant board for 15 minutes a day.
Nutritional Supplementation: The following supplements are essential for healthy hair growth: flaxseed oil, biotin, niacin, vitamin B complex, folic acid, vitamin B5, PABA (para-aminobenzoic acid), silica, iron, trace minerals, and zinc. Free form amino acids, especially cysteine, can also be helpful, as can kelp tablets, desiccated liver, and thyroid glandulars.
Although elevated levels of copper can lead to brittle hair and split ends, low copper levels can also result in hair loss, and should therefore also be considered.
Topical Treatment: Rub castor oil into the scalp for ten minutes, then apply a hot damp towel for 30 minutes, and then cover your head with a plastic shower cap and keep in place overnight. The next morning, wash out your hair. Do this for two nights, then, repeat this using extra virgin olive oil for two nights, then use wheat germ oil for two nights. Rest one night and repeat seven-day cycle.
Apple cider vinegar used as a hair rinse can also help stimulate hair growth.
Best of health to you
