MUTATIONS AND GENETICS

Darwin said survival of the fittest, is the key to evolution. Hence nature itself selects organism. Mutation is one of the main factor for evolution .Mutation can be refer to the error in gene or genome sequencing that can be of some loss but not always .It is of benefit as well. A mutation can make individual more efficient or less efficient. YES!! We all do have mutants around us that are not fiction or movie like X-MEN. Mutants are those who has problem in gene prior and after birth. 

                                                 

Now other factor for evolution is the genetic constituent. So guys can u think of what we are made of yes obviously cells but what does it constitute off. Now don’t think of any bookish knowledge .Have not you heard people saying oh he has his father’s height, oh my god she is just as fair as her mother etc .yes actually we inherit qualities that have been passed on to generations in our family and how it passes ?? Well Mendel called it factors, we now call it genes. Genes thus carries information that is inherited.

                                                      

Just think if we were in place of Mendel ,we would have been called as father of genetics. Well guys easier said than done, earlier his logic was not even considered .He got recognition after a long time.
