For example, we know that mutations disrupt the equilibrium of allele frequencies by introducing new alleles into the population, in the same light, natural selection and non-random meeting disrupt the Hardy Weinberg equilibrium because the resultant changes in gene frequencies, this occurs majorly because certain alleles help or harm the reproductive success of the organisms that carry them.Īnother factor that can disrupt this equilibrium is genetic drift, now we all know that in small populations, phenomena occur by chance where allele frequencies grow higher or lower, this contributes to genetic drift, which can also be called genetic disruption. This equilibrium can be distributed by a number of forces such as mutations, natural selection, non-random meeting, genetic drift and gene flow. Now there are similar explanations and contradictory explanations of the working of genetic variation but according to Hardy Weinberg equilibrium principle it is stated that the genetic variation in population will remain constant from one generation to the next in the absence of disturbing factors so in biological terms this theory explains that when meeting becomes random in a large population present with no disruptive circumstance, the law predicts that both genotype and alleles frequencies will remain constant because they are in perfect equilibrium. With the given perception and its realisations alongwith its discoveries of the previous 20 years have led to a evident increase in the number of people and organisations that are involved in human genetics. The findings that we gather by studying genetic composition of a human body increases our motivation in light of our growing and understanding of the contribution that genes in particular make to the development of diseases such as cancer, heart disease, mental health illnesses and various other diseases and abnormalities. The study of human genetic variation is not confined to one thing, for but we learn about human genetics variation and its sources and transmission inevitably contributes to our understanding of genetics in general, by understanding the genetic composition and its variation in other species informs and expands our understanding of our own bodily compositions.Īnother important reason for understanding human genetic variation is the discovery and description of the genetic contribution to many human diseases. ![]() Why is it so important for us to understand and read about human genetics? One of the simplest explanations would be an interest in understanding ourselves better and allowing ourselves to know the composition of our body or the genetic composition of our body and the inheritance through which various predictions can be made. ![]() Genetics can be called the scientific study of inherited variation in human beings, by this we can say that human genetics is the scientific study of inherited human variation. Before understanding the Hardy Weinberg law we must understand genetics in a very elaborate manner so the Core characteristics of the law is easily understandable by us.
