Trisomy 18, also known as Edwards Syndrome, is a genetic disorder caused by the presence of all or part of an extra chromosome 18. It is typically inherited from one of the parents; the mother is more likely to pass it on than the father.
Maternal Inheritance
Trisomy 18 occurs when an extra chromosome 18 is present in every cell of the body. The extra chromosome can come from either the mother or the father. If the extra chromosome is inherited from the mother, the condition is referred to as maternal trisomy 18. Maternal trisomy 18 occurs when the mother has an extra chromosome 18 in some or all of her eggs. This extra chromosome can be passed on to the child during conception.
Paternal Inheritance
Paternal trisomy 18 occurs when the extra chromosome 18 is inherited from the father. In this case, the father has an extra chromosome 18 in some or all of his sperm. When the sperm fertilizes the egg, the extra chromosome is passed on to the child. This type of trisomy 18 is much less common than maternal trisomy 18.
Diagnosis and Treatment
Trisomy 18 can be diagnosed prenatally through amniocentesis or chorionic villus sampling. It can also be diagnosed after birth through physical examination, genetic testing, and chromosome analysis. There is no cure for trisomy 18, but there are treatments available to help manage the symptoms. Treatment may include physical or occupational therapy, speech therapy, medications, and surgery.

Trisomy 18 is a genetic condition which occurs when a baby has an extra chromosome, specifically chromosome 18, in some or all of its cells. Trisomy 18 is caused by an error in cell division and can be inherited from either the mother or the father, or can occur spontaneously in the baby. The risk of trisomy 18 increases with the age of the mother, but it can happen to anyone.

Trisomy 18 is a chromosomal abnormality that occurs when an individual has three copies of chromosome 18 instead of the usual two. This condition typically occurs due to an error in the genetic material that occurs during the formation of the egg or sperm cell in a parent. Therefore, trisomy 18 is caused by an abnormality in the parent’s genetic material, rather than being inherited from either parent. This means that trisomy 18 is not passed down from either the mother or the father, but is instead a random result of an error in the genetic material of the parent.

Trisomy 18 is a genetic disorder caused by a chromosomal anomaly, which occurs when a baby has three copies of the eighteenth chromosome instead of the usual two. It is a relatively rare disorder, occurring in only 1 in 5,000 live births.
In most cases, trisomy 18 is not inherited, but rather occurs as a random event during the formation of reproductive cells in either the mother or the father. It is not related to any known lifestyle or environmental factor. The mother's age at the time of conception is a factor, however, with older women being at higher risk.
Trisomy 18 is caused by an extra chromosome 18 in every cell of the body. In most cases, this extra chromosome is inherited from the mother, and is known as maternal trisomy 18. In a small number of cases, the extra chromosome is inherited from the father, and is known as paternal trisomy 18.
In conclusion, trisomy 18 can be inherited from either the mother or the father, although in most cases it is inherited from the mother. It is important to note that trisomy 18 is not associated with any known lifestyle or environmental factors, and is a purely random event.

It is a chromosomal disorder that is typically not inherited from either parent, but instead occurs as a random event during the formation of reproductive cells. The extra chromosome present in trisomy 18 occurs as a result of an error in cell division, either during the formation of the egg or the sperm or in early fetal development.
Trisomy 18 can be caused by an extra chromosome 18 inherited from either the father or the mother. In most cases, the extra chromosome comes from the mother, however, there have been documented cases where the extra chromosome has come from the father. The exact cause of the extra chromosome in either case is unknown, though it is believed to be due to a random error in cell division.

Trisomy 18 is caused by an extra chromosome 18 present in all or some of the body’s cells. It is a random event that can occur during the formation of reproductive cells in either the mother or the father, and is not inherited from either parent.
