The profound scope of the things dependent on the genes of an individual makes it such that to ignore genetics would be certain extinction for a species. For example, certain illnesses are propagated or inherited via genes. The son of a diabetic or dementia sufferer will most likely have the same fate. Although, the susceptibility will not mean certainty, oftentimes, the illnesses require a trigger to manifest in the bodies of the heirs.
To truly study the workings of the genetics of humanity, we must first understand humans and how we interact with our genetic framework. Most importantly, our interaction with diseases that stem from our genes. Examples of such interactions is the case of inherited hemophilia among European royals and the predisposition to sickle cell anemia in the African and Caribbean families. Certain diseases are predominant in gene types and certain people will continue to produce offspring certain who will suffer the same fate.
These illnesses could either be caused by a single gene; monogenic, or a group of genes; polygenic. Polygenic diseases have two forms, they are either a group of genes responsible for the illness, or single genes scattered along the genome. Monogenic and Polygenic illnesses based on a group of genes usually result in rare and/or strange conditions such as Down Syndrome and the likes, but the Polygenic illness that caused by scattered genes on the genome results in much more constant and dire conditions. Some of the conditions that may be suffered with Polygenic illness include: infertility, obesity, cancer, etc., and are particularly difficult to treat or cure.
But the fear remained nonetheless and led many parents seeking prenatal testing to know if their kids would turn out fine or at least normal. A rise in abortions followed as parents found out their babies weren't developing right due to a mutation. As a result, the discoveries of mutations gave rise to new form of eugenics, where only eliteindividuals with desirable genes were to be bred moving forward. This new form of eugenics – newgenics, not as savage as its predecessor and implemented at sperm banks. This meant they only accepted donations from those with these"elite" genes.
But with more studies came more and more complexities in the gene conundrum. Since the bane of gene sequencing and mapping was solely centered around cracking the code of inheritance and how to eradicate dire illnesses/diseases, scientists were able to understand certain conditions and pinpoint the actual gene or genome responsible for them.
