Heredity: all the traits and properties that are passed along biologically from both parents to child. To some degree this determines your general level of health. You inherit physical traits such as the color of your hair and eyes, shape of your nose and ears, as well as your body type and size.

Food provides energy for physical activity. As you get more active and more fit, and/or as you lose weight, your energy needs (how many calories you need) may change. To get the energy you require, you need to get the proper amount of: Protein, which is needed to maintain and rebuild tissues such as muscles.

Heredity influences several factors that contribute to fitness, such as body size and muscle fiber composition. Whether we are tall or short is determined by heredity. The percentage of slow-twitch and fast-twitch muscle fibers found in skeletal muscle is determined genetically.

The range of personal, social, economic, and environmental factors that influence health status are known as determinants of health….About Determinants of Health

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.
• Thalassemia.
• Cystic Fibrosis.
• Tay-Sachs disease.
• Sickle Cell Anemia.
• Learn More.
• Recommended.
• Sources.

There are three types of genetic disorders:

• Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
• Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed.
• Complex disorders, where there are mutations in two or more genes.

Genetic disorders

• Albinism. Albinism is a group of genetic conditions.
• Angelman syndrome. A rare syndrome causing physical and intellectual disability.
• Ankylosing spondylitis.
• Apert syndrome.
• Charcot-Marie-Tooth disease.
• Congenital adrenal hyperplasia.
• Cystic fibrosis (CF)
• Down syndrome.

Sickle cell disease is the most common inherited blood disorder in the United States, affecting around 100,000 Americans, most commonly in African Americans. There is a 25% chance that a child will be born with sickle cell disease if both parents have the defective gene.

Four of the main types are:

• Single-gene inheritance diseases.
• Multifactorial genetic inheritance disorders.
• Chromosome abnormalities.
• Mitochondrial genetic inheritance disorders.

According to the Journal of Molecular Medicine, Ribose-5 phosphate isomerase deficiency, or RPI Deficinecy, is the rarest disease in the world with MRI and DNA analysis providing only one case in history.

Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

Gene Therapy – Attempts to “Cure” Genetic Disease The only real option right now to fix genetic diseases is to use gene therapy. In gene therapy, the “good” version of a gene is introduced into a patient’s DNA. The hope is that this healthy copy of the gene will overcome the problems of the disease version.

Genetics, Disease Prevention and Treatment FAQ

1. Check regularly for the disease.
2. Follow a healthy diet.
3. Get regular exercise.
4. Avoid smoking tobacco and too much alcohol.
5. Get specific genetic testing that can help with diagnosis and treatment.

A geneticist who meets with patients to evaluate, diagnose, and manage genetic disorders is a doctor with special training in genetics, also called a clinical geneticist.

Conditions That Are Hard to Diagnose

• 1 / 14. Irritable Bowel Syndrome. This condition causes pain in your belly area and changes in bathroom habits that last at least 3 months.
• 2 / 14. Celiac Disease.
• 3 / 14. Appendicitis.
• 4 / 14. Hyperthyroidism.
• 5 / 14. Hypothyroidism.
• 6 / 14. Sleep Apnea.
• 7 / 14. Lyme Disease.
• 8 / 14. Fibromyalgia.

Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease. Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are limitations.

Laboratory tests, including genetic testing: Molecular, chromosomal, and biochemical genetic testing are used to diagnose genetic disorders. Other laboratory tests that measure the levels of certain substances in blood and urine can also help suggest a diagnosis.

Some disadvantages, or risks, that come from genetic testing can include: Testing may increase anxiety and stress for some individuals. Testing does not eliminate a person’s risk for cancer. Results in some cases may return inconclusive or uncertain.

Genetically, you actually carry more of your mother’s genes than your father’s. That’s because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.

And, mitochondrial DNA (or mDNA) is inherited strictly from the mom. Because mDNA can only be inherited from the mother, meaning any traits contained within this DNA come exclusively from mom—in fact, the father’s mDNA essentially self-destructs when it meets and fuses with the mother’s cells.

As we’ve learned, dads contribute one Y or one X chromosome to their offspring. Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother. Remember, girls inherit two X chromosomes—one from mom, one from dad.

8 Traits Babies Inherit From Their Mother

• Sleeping Style. Between tossing and turning, insomnia, and even being a fan of naps, babies can pick up on these from mom during nap time and turn them into their own lifelong sleep habits.
• Hair Color.
• Hair Texture.
• Temper.
• Healthy Eating Habits.
• Dominant Hands.
• Migraines.
• Intelligence.

The genetics of height Genes aren’t the sole predictor of a person’s height. In some instances, a child might be much taller than their parents and other relatives. Or, perhaps, they may be much shorter.

Draw your arms towards to toes or to the knee flexor and grab your foot or shoe. Pull behind your body and touch your back. This easy and effective exercise will stretch the knee joints and give you additional height. Read more on stretching to grow taller.

Another way to estimate a child’s adult height is to double a boy’s height at age 2 or a girl’s height at age 18 months. Remember, a child’s height is largely controlled by genetics. It’s also important to note that children grow at different rates.

The average American woman is 5’4″, so 5’6″ is considered tall for a woman.
