Human Genetic variation

Human genetic variation is that the genetic variations in and among populations. There is also multiple variants of any given cistron within the human population (alleles), a state of affairs referred to as polymorphism. No two humans are genetically identical. Even monozygotic twins (who develop from one zygote) have infrequent cistrontic variations thanks to mutations occurring throughout development and gene copy-number variation. variations between people, even closely connected people, are the key to techniques like process. to be told the fundamental genetic mechanisms that determines the traits expressed by people in a very population
