What is heterozygous? 

Heterozygous meaning is an amazing new method of sex determination that could potentially help an estimated 20 million people worldwide. The method developed by scientists at the University of California San Francisco uses a unique combination of DNA techniques and mathematical modeling to accurately determine if a woman is a carrier of the X and Y chromosomes the ones that produce male characteristics even when she carries no genes for either condition. To put it simply, it eliminates the guesswork and gives parents-to-be a more accurate idea of whether their child will be healthy enough to survive on their own. If this seems like a confusing description of a person, imagine a twin with two different sets of genes for hair color. Their color might go with one set while their eye color goes with another. A person can have two different Heterozygous genes but not two completely different genes. In this context "heterozygous means having the same set of genetic instructions on one copy of each gene compared with

Heterozygous is a term used in genetics to describe the pairing of a diploid (2n) sperm and an ovum. Most genetic relationships involve one individual being a carrier of a particular gene while the other is not. In this case, one individual is a carrier for the gene for heterozygous (as opposed to homozygous, when an individual carries one gene but not the other) and the other is not. The commonest example of this is how people get blue eyes despite being born with green eyes. parents that are heterozygous for having freckles dominant are crossed. which correctly describes their offspring

The term heterozygous refers to one individual having one set of genes for a characteristic and another set for another characteristic. In an unrelated species, such as the human, heterozygous animals are often considered to have all of the associated normal traits without having one particular abnormal trait that frustrates or confounds those around them. parents that are heterozygous for having freckles dominant are crossed. which correctly describes their offspring as twenty-five percent have freckles. twenty-five percent are ff. seventy-five percent have freckles. seventy-five percent are ff. 

Heterozygous (or genetic) means having two copies of the abnormal gene for the same specific gene. Homozygous status only occurs in individuals who carry one abnormal gene and one normal gene for each type of body part. That means that the normal genes help control the growth and development of body parts, but the abnormal genes control who you ultimately become. For example, someone who carries one normal gene for an eye may develop sight with total darkness if the abnormal gene is present in his or her body, but not if it is eliminated. An example would be ARA syndrome, a disease that causes muscular problems although many people are carriers of this gene. All carriers of the gene for ARA have some level of the disease, but someone who doesn't carry the gene can only develop the symptoms of the disease if they have another person with the gene. Heterozygote (meaning ‘incompatible’) is a term used in genetics to describe individuals who carry one particular gene but not the other. Homozygotes can have all the good parts of a normal gene and none of the bad parts. They are exactly as healthy as any other person carrying the normal gene. However, they carry the x chromosome, which contains the abnormal gene.

Heterozygous means having two copies of the gene for a particular trait. It's uncommon in humans, but it's common in some animals, primarily horses and cattle. Such animals have a trait that makes them more useful to their breeders. For example, there's been some research showing that Latino dogs have an increased likelihood of being heterozygous for certain genes that make their hearts more efficient at pumping blood. And that important trait means that they're likely to have more energy and longer lives than their un-heterozygous brethren.

It is an old term used to describe individuals who have two copies of a particular gene. This can be either from maternal or paternal parents. The idea is that while an individual's existence itself might be predetermined - designed - when it comes to the choices they make as individuals, their genes can also determine what sort of person they might become.

Such traits can include eye color, hair color, and the like. Most people carry one copy of the gene for blue eye color, for example, while others may have one copy of the gene for dark hair. Individuals with two copies of the gene for light hair often develop coarse or loose hair due to the accumulation of dirt and oil in their hair follicles.

Heterozygous familial hypercholesterolemia

"heterozygous familial hypercholesterolemia" is a condition that leads to very high cholesterol levels. The affected individuals have one or more copies of a defective gene for FH, a form of lipoprotein lipase. As a result, their bodies are unable to properly dispose of triglycerides (fats) as they are transported to the liver where they can be absorbed so they can be damaged and eventually leading to heart disease. The risk of cardiovascular complications increases when individuals carry two copies of the FH allele compared to one.

See my post on cholesterol, #1 cause of death in adults in the United States. This is a condition called "heterozygous familial hypercholesterolemia" which can cause heart disease and stroke. The condition is caused by a gene mutation that results in a lack of HDL cholesterol which protects against heart disease. The most common symptom of heterozygous familial hypercholesterolemia is abdominal obesity which can begin at any age.

"heterozygous familial hypercholesterolemia" is one of the most common genetic traits resulting from an error in the FTO gene that encodes for a component of LDL cholesterol, or "bad" cholesterol. As adults, people with HFE tend to have higher cholesterol levels and may be particularly at risk for cardiovascular diseases like heart attacks and strokes. While everyone has some LDL cholesterol, those with HFE tend to have much heavier levels of it

Heterozygous familial hypercholesterolemia (HFT) is a rare genetic disorder that leads to extremely high cholesterol levels. The condition can cause you to develop heart disease at an early age, thereby placing an enormous financial strain on your family. If you are interested in learning more about this condition, please visit: www.heart.org/haem/familial.

There are many different types and degrees of HFE, also known as heterozygous familial hypercholesterolemia or HPE. Sometimes known as familial hypercholesterolemia type 1, it is characterized by high levels of HDL cholesterol (the good) and low levels of LDL cholesterol (the bad). FH tends to develop at a young age, typically between the ages of 15 and 25. Though it can affect any family member with risk factors for heart disease, commonly diagnosed risk factors include being male, having a family history of heart disease or having obesity and smoking tobacco

the resulting cholesterol levels in people with heterozygous FH have been reported as being as high as 1.5 mmol/L (about 400 mg/dL). Subjects with homozygous FH have been reported to have cholesterol levels as high as 1.33 mmol/L (about 300 mg/dL) when measured using enzymatic methods which utilize standard techniques. These values are substantially greater than those previously reported for subjects without FH. As a result, subjects with FH have been reported to have coronary heart disease as well as stroke components that account for approximately 30% of all cases

Heterozygous familial hypercholesterolemia (FHTH) is a condition that causes your fat to become more sticky. As a result of feeling hungry and burning fat stored in your liver, your cholesterol levels can rise. Cholesterol is needed by your body to make new cells and process fats. If your cholesterol levels become too high, this can lead to serious health issues, including heart disease and stroke. The best way to lower your cholesterol levels is by getting on top of all the tips listed above -

Heterozygous FH is a condition that increases your heart's risk factors for developing heart disease. The risk of heart attack or stroke increases six-fold when a person has this genetic condition. Despite this risk, children born to parents with Heterozygous FH are 15 times more likely to develop heart disease than children born to parents who don't carry this gene. Until recently, there have been no effective treatments available to reduce the risk of these complications in newborns.

The heterozygous form of familial hypercholesterolemia is the most common genetic heart disease in people of African descent. It causes the cells in your liver to become abnormal and grow quickly. If you have the heterozygous form, your risk for heart disease is around 30 percent, but it can be as high as 60 percent in those who have one copy of the normal gene for the enzyme LDL receptor. The good news is that most people will never develop this disease, but you can effectively prevent it from happening by eating healthy, exercising regularly, and getting your cholesterol tested regularly.

HSM is a rare, inherited disorder that causes the body to produce too much cholesterol. Cholesterol in the blood can clog lead arteries and cause heart disease. If you have HSM and have been told by your doctor that you need a cholesterol-lowering drug, there is a good chance you will benefit from one of these cholesterol-lowering drugs.
