Samaira Azim Biology Fahmida Ahad M2. Discuss the impact on individuals and society of genotypes resulting in developmental delay or impairment of normal body functioning Downs syndrome is a disorder which is not hereditary, meaning it does not run in the family, but is still a genetic problem in the sense that Downs syndrome is caused by having the extra chromosome 21. Downs syndrome affects many aspects of an individual?s life depending on the type they are born with. There are3 different types of Downs syndrome such as 1. Full Trisomy 21- where all the cells have a third 21st chromosome in them. 2. Mosaic DS- where there are two cell lines which mean there are some cells that have the normal 46 chromosomes and some cells that have an additional 21st chromosome, creating 47 chromosomes in total, which creates a mosaic like pattern. ...read more.

Every child is different therefore is difficult to predict each individuals outlook, but overall with the right support people with downs tend to live happy lives. Cystic Fibrosis Cystic Fibrosis is a condition which is caused by a mutation in the CFTR gene. This specific mutation causes excessive amounts of salt and water to enter the body?s cells. This results in a build-up of thick, sticky mucus in the body's tubes and passageways, including the lungs, digestive system and other organs, resulting in the symptoms of cystic fibrosis. These symptoms include: ?persistent cough ? Re-occuring infections affecting the lungs and chest ? Difficulty in gaining wait 1. Difficulty in breathing ...read more.
