Detailed explanation-1: -The environmental conditions (stress, pesticides), individual genotype (genomic and mitochondrial DNA) and stochastic factors can induce genetic and epigenetic alterations that cause a decline in somatic stem cell function that can be the origin of metabolic, degenerative diseases, cancer and aging in the individuals.
Detailed explanation-2: -Results: Individual differences primarily reflected individual specific environmental influences at all ages. The increase in total variance across age groups was primarily due to genetic influences in the age groups 45–74 years and greater environmental influences in the oldest age group (>74).
Detailed explanation-3: -Your genes hold the basic instructions for your body to grow and function, but they are far from the only thing controlling your traits. Most traits are shaped both by a person’s genes and by environmental factors. Environmental factors include everything outside of DNA that affects your traits.
