These studies demonstrated the significant contribution of unbalanced chromosomal karyotypes to pregnancy failure. an extra copy of chromosome 21. Triploidy is the presence of an additional set of chromosomes in the cell for a total of 69 chromosomes rather than the normal 46 chromosomes per cell. This causes physical. The term “mosaic” indicates that some cells contain the extra chromosome 22, whereas others have the normal chromosomal pair. The number of chromosomes, as well as the number of chromosome sets, can vary due to various mechanisms that occur in the sexual reproduction. Autosomes are numbered according to. Normally, humans have 46 chromosomes arranged in 23 pairs; the pairs vary in size and shape and are numbered by convention. 2. However, characteristic features include growth deficiency after birth. The major features of this condition include distinctive facial features, sleep disturbances, behavioral problems, mild to moderate intellectual disability, and delayed speech and language skills.
