How many DNA molecules are present in one chromosome 1/2 1 2 None of the above. None 4. None 5. Which of the following does not contribute to the differences between the individuals of the same species are primarily attributed to Allelic variation Mutations in particular genes Influence of the environment Genetic drift None 6. Which of the following is NOT true for the effect of environment on the gene function and the development of the individual? Genomic composition can alone dictate structure of the individual Gene products function in coordination with the environment Traits like the skin color may stay unaffected in different environment Change in the environment does not lead to change in the gene expression None 7.
