Human genetics And Its Role

Human genetics is the basis of the inheritance in human beings. Encompassing a wide variety of overlapping fields that include classical genetics, molecular genetics and multiple other types of genetics, it is a very important aspect of biological science. Genes play an important role in shaping what we are today and for all our so-called genetic traits. The genetic information of parents is passed down to their children, grandchildren, or even great grandchildren. Similarly we have also inherited a number of genetic traits from our ancestors. All our physical characteristics, personality traits, and talents can be the result of the genetic makeup of our ancestors. Genetics PPT Templates will make more understandable about human genetics and its importance.

As we know we have 23 pairs of chromosomes in almost every cell in our body and 22 pairs of chromosomes are same in men and women excepting 23rd pair. It has been figure out in Genetics PPT Templates and has been described in a systematic way to get you more and more. Each pair consists of a chromosome from our mother and a chromosome from our father. The chromosomes carry genes, which are the segments of DNA that determine factor a whole range of characteristics. The color of our hair, our height, and even our predisposition to health concerns are some of the genetic traits that we have inherited from out parents. 

Genetic information is contained in the genes of a person and as the cells of the body duplicate, the genetic information is passed to the new cells. In our genetic makeup, certain genes are dominant and influence the genetic trait of a person even if only one copy of that dominant gene is present in that pair of chromosomes. On the other hand, certain genes are recessive and do not affect the genetic trait of a person even if they are present on both chromosome pairs. In most cases genetic diseases can be avoided by up to 70% if the exposure to known environmental triggers of the condition is avoided. For example, spinal bifida (a neural tube defect) in newborns can be avoided if their mothers take folic acid during early pregnancy and continue taking it until their doctor advises them to stop. Genetics PPT Templates is the right place where one may get relevant information about human genetics and basis of the inheritance in human beings.
