The chromo virtually is said to be more than snitch . A normal human chromosome is born with 46 chromosomes . after(prenominal) concept , the fertilized egg begins to divide . Each new cellular p honephone pull up stakes impart a matching! set of chromosomes and from each one cell will therefore have the same all-time genetic code as the for the first time cell . In Down syndrome the chromosomes in the very early cells do not partner off off correctly .These chromosomes are 22 pairs cocksure 2 sex chromosomes . Instead of having 46 chromosomes , a somebody with Down syndrome has 47 chromosomes (Selikowitz , 1997 .

The history of Down syndrome can be dated back since 1505 precisely and recognized in 1866 . Down syndrome was named after Dr . John Langdon Down . He was the first who describe the characteristics feature of the syndrome but the cause was not unless clear . It was in 1932 when it was said to be abnormalc y of the chromosome but only in 1959 when it was confirmed that it was by an duplication chromosome (Selikowitz , 1997 ) at that place are 3 types of down syndrome . archetypical is known as Trisomy 21which is the most common form of Down syndrome , affecting virtually 94 of people with the syndrome . Here , the feature chromosome aligns itself with the 21st pair of chromosomes (hence Trisomy 21 . Although we do know that Trisomy 21 is not genetical , we do not know what causes this particular cell discrepancy . Second is known as photomosaic down syndrome which affects well-nigh 4 of people with the syndrome . Here , some cells divide wrong while others will continue to retch normally . This produces a mosaic pattern or a mixture of cells , where some have 46 chromosomes and some have 47 (as in Trisomy 21 . The proportion of normal cells and Trisomy 21 cells will deviate greatly from...If you want to get a full essay, fiat it on our website: OrderEssay.net
