Scientists have been performing experiments and presenting different theories about human development,some are acceptable and have great impact on our lives.The characteristic futures of a person or entire popuplation depends on their genes which they carry from their parents.Some cases it is true but not same in all individuals.Homosapiens have learnt and adopted alot during their evolution.But on a wide perseptive traits cannot be change.
According to me,Genetic material does have a great role in geneotype and phonotype of a newborn,but enviornmental factors are equally important.For instance people living at high altitude have more heamoglobin in their blood as compared to those who are at low altitude this is the survival extinct which a person evolve in itself for survival.So in these cases no such role of genes.
Some of the individuals like children with Down sydrome and Autism having low IQ levels,poor development are the prime examples in which genes have affected the trait and we cannot do much to change the conditions.Another fact which supports this fact is newborn babies with Thalassemia they have low heamoglobin in their blood and need regular transfusions for survival.
In my opinion,babies learn from their parents,how they treat them and what type of surroundings do they provide them during their growth it matters alot,because they learn what they see,how to talk how to eat and how to obey your elders these are the things training play a crucial role.
In my conclusion,I fully agree with the statement the human nature or charaters which encoded in their genes cannot be changed becuase we cannot change the genetic material and the inforation they carry.A small area where habits of a person can be changed but not as much as to create a difference.
