Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
A cortical defect is an abnormality in the outer shell.
recessive defect meaning that both copies of the chromosome must have the defect before it can be expressed. Females who have one X chromosome without the defect do not get this disease. Males, since they only have one X chromosome, get the disease
A abnormality in the size, shape, or number of chromosomes.
Meckel's diverticulum is not hereditary. It is a vestigial remnant of the omphalomesenteric duct, an embryonic structure that becomes the intestine. As such, there is no genetic defect or abnormality.
An underlying pathologic defect refers to a fundamental abnormality or dysfunction in the body's structure or function that contributes to a disease or health condition. This defect can be genetic, developmental, or acquired, and it often sets the stage for the manifestation of symptoms or complications. Identifying the underlying defect is crucial for diagnosis and treatment, as it helps healthcare providers target the root cause rather than just addressing the symptoms.
its when seven genes chromosome 15 are missing or ununexpressed on the paternal chromosome.

The defect of having a third chromosome 21 is known as Trisomy 21, which causes Down syndrome. This genetic condition leads to intellectual disabilities, characteristic facial features, and an increased risk of certain health issues.
The chromosomal defect you are describing is known as a translocation. In a translocation, a segment of one chromosome breaks off and is reattached to a different chromosome, which can lead to genetic imbalances and various genetic disorders. This type of defect can occur in both somatic cells and germ cells and is often associated with certain cancers and congenital conditions.
Hemophilia is a genetic mutation of the sex-linked X chromosome.
This is a birth defect. A person born with this has an extra chromosome 21.
