Each cell in your body contains chromosomes, which contain your genetic material in genes. Within each cell there are thousands of genes. We inherit 23 pairs of chromosomes from our parents and genetic disease is caused by an abnormality of a gene or entire chromosome. These abnormalities include:
The human body prefers the exact number of genes, completely intact. If this is not the case, genetic abnormalities occur, which can lead to miscarriage or the birth of a child with a congenital disease or defect.
Comparative Genomic Hybridization (CGH) is the newest technology in genetic screening that analyzes genetic material from an embryo to determine its genetic make-up. CGH is able to screen for more genetic problems and has a faster turnaround time than PGD.
