So Is It All In The Genes? What is Heredity?

Though the question of heredity is on the minds of many people including parents in regards to passing on traits through their own genetics, the studies show that scientists are soon going to be able to identify and possibly treat any medical abnormalities prior to conception. Though this medical breakthrough may take many years, the studies of how genes are transferred through procreation are steadily making huge advances in how a particular gene can only be transmitted through genetics and how if caught early a potentially dangerous gene can be suppressed and possible eliminated through early diagnosis.

THE BASICS

Heredity is basically passing different characteristics from one generation to the next, the obvious effect being the feature similarities between father and mother to their offspring. For instance this is the reason why offspring often look like their parents in their physical appearance such as skin and hair color as well as height, bone structure as well as many other individual traits.

A cat gives birth to a kitten, and a dog has a puppy and though their offspring may share a lot of the same physical qualities as their parents, it now may go even further as it has been shown that also aside from the similar physical aspects, other physiological traits may also be passed on to their offspring. The subject of heredity comes into play with many living organisms like animals, plants, fungi, bacteria and protists. It really comes down to genetic sequencing, and sometimes the genetic code can be broken down. This is a specific field of study that is called genetics and is studied by highly qualified scientists called geneticists.

When broken down, cells are the basic units that structure all living things. When examined closely tiny biomechanical structures called genes are what carry individual traits that are passed on from one generation to the next. This is the study of DNA (deoxyribonucleic acid) where the genes individual chains called chromosomes can now actually be pinpointed revealing facts about individuality. Basically genes are the blueprints that are responsible for the construction of cells that make up the tissue, organs and the body itself. These genes create thousands of proteins that are made of smaller units called amino acids and are the building blocks that are responsible for inherited traits such as hair, blood types and even physical similarities as these genes can be passed on to offspring.

ScientistS have proven that genes from both parents can be passed on but not necessarily develop in the offspring. On the flip side not only can physical traits be passed on but also diseases whether the parents are symptomatic or not. If both parents carry the dysfunctional gene the risk of genetic disease greatly increases. Some of the most common genetic disorders include Tay-Sachs disease, cystic fibrosis, Down syndrome, muscular dystrophy, sickle cell anemia, spina bifida and hemophilia to name a few.

Science is advancing to the point that they can diagnose many diseases early and determine when there is a chance of inheriting a hereditary disease.
