Question

Would the manifestation of a trait be affected by the DNA nor the genes are altered

Answer 1

Answer: The manifestation of a trait can be altered by the environment along with the DNA or genes.  

*As we know, the DNA or the genes play a major role in the manifestation of each trait in living organisms.

*However, some of the traits are influenced by the environment as well. Examples of such traits include weight, size, height etc.

*Hence, the manifestation of a trait can be affected even if the DNA or genes are not altered, provided that the trait is influenced by the environment.

Answer 2

Answer:

The manifestation of a trait can be altered by the environment along with the DNA or genes.

Explanation:

The genotype of DNA within a human cell serves as a blueprint for directing a variety of processes involved in the formation of an embodied organism. Although we frequently treat the human genome as if it is fixed, there is a great deal of variation among individuals. The observable human phenotype is made up of multiple traits that are the result of many genetic variants within a single genome. Polygenic traits include hair, eye and skin colour, height, build, and behaviour. Many of these traits can be modulated by our environment, such as stress, sunlight, or microbes, resulting in a variety of outcomes. This special issue broadens our understanding of genotype and phenotype and delves into recent advances in understanding the factors that influence human phenotypic development.

We investigate cases in which DNA mutations or epigenetic changes specify various cells and traits, but we also highlight cases in which phenotype is influenced by suites of genes and gene products from commensal bacteria. This special issue highlights the various approaches that, when combined, are improving our understanding of the complex relationship between genotype and phenotype, with the potential to lead to discoveries that benefit human health.
