This is trisomy 21 i.e. Downs syndrome
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
Hemophilia is a genetic mutation of the sex-linked X chromosome.
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.
The chromosomal defect caused when part of a chromosome breaks off and reattaches backward on the same chromosome is known as an inversion. Inversions can disrupt gene function and regulation, potentially leading to various genetic disorders or developmental issues. They may not always result in visible phenotypic changes but can affect the offspring if they occur in germ cells.
Hemophilia, a blood clotting disorder, is an example of a sex-linked recessive defect. It occurs more commonly in males because the gene for hemophilia is located on the X chromosome. Females are usually carriers of the gene but are less likely to exhibit symptoms.
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
Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
A growth defect in cells is called you !

"Congenital" means present at birth. So, a congenital heart defect is a defect (structural anomaly) that is present at birth. 1 in 100 babies are born with a congenital heart defect.
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.
The chromosomal defect you are describing is known as a translocation.

its when seven genes chromosome 15 are missing or ununexpressed on the paternal chromosome.
Exposure to an infection, including German measles (rubella), cytomegalovirus, tuberculosis, syphilis, or toxoplasmosis; A birth defect (like a severe cardiovascular defect); A chromosome defect
Defect cascading explains how one defect leads to other defects. For Example, employee application salary calculations are not correct when totaling Basic, Tax and Gross, so for this issue defect raised. In this case other modules will block and also same defect will exists in all those modules due to this defect. This is called Defect Cascading.
a defect of the body present from birth
