A Robertsonian translocation in balanced form results in no excess or deficit of genetic material and causes no health difficulties. In unbalanced forms, Robertsonian translocations cause chromosomal deletions or addition and result in syndromes of multiple malformations, including trisomy 13 (Patau syndrome) and trisomy 21 (Down syndrome). The ...
Chromosomal reciprocal translocation of the 4th and 20th chromosome. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation.
There are two main types of translocations: Reciprocal translocation: Segments from two different chromosomes have been exchanged. Robertsonian translocation: An entire chromosome has attached to another at the centromere - in humans, these only occur with chromosomes 13, 14, 15, 21, and 22.
Translocation Down syndrome can be de novo; that is, not inherited but occurring at the time of an individual's conception, or may be inherited from a parent with a balanced translocation. The balanced translocation figure shows a 14/21 translocation between the long arms of chromosomes 14 and 21, where the other chromosomes are not shown.

The most serious charge against the man accused of killing the UnitedHealthcare CEO in broad daylight last week on a Manhattan sidewalk is murder in the second degree. Given the image of the ...
In a translocation heterozygote, the two haploid sets of chromosomes do not carry the same arrangement of genetic information. As a result, during prophase of the first meiotic division, the translocated chromosomes and their normal homologs assume a crosslike configuration in which four chromosomes, rather than the normal two, pair to achieve ...
Myth No. 2: You can access 100% of your home’s equity with a home equity loan or a HELOC. Unfortunately, very few lenders will finance a loan for 100% of your home equity.
